/* The goal of this routine is to free as much CPU as possible without
   loosing too much sound quality.  We would like to know how long a note
   has been playing, but since we usually can't calculate this, we guess at
   the value instead.  A bad guess is better than nothing.  Notes which
   have been playing a short amount of time are killed first.  This causes
   decays and notes to be cut earlier, saving more CPU time.  It also causes
   notes which are closer to ending not to be cut as often, so it cuts
   a different note instead and saves more CPU in the long run.  ON voices
   are treated a little differently, since sound quality is more important
   than saving CPU at this point.  Duration guesses for loop regions are very
   crude, but are still better than nothing, they DO help.  Non-looping ON
   notes are cut before looping ON notes.  Since a looping ON note is more
   likely to have been playing for a long time, we want to keep it because it
   sounds better to keep long notes.

/* Eric's explanation for the FIXME (March 2004):
 *
 * I don't have the original email from my archived inbox, but I found a
 * reply I made in my archived sent-mail from 1999.  A September 5th message
 * to Masanao Izumo is discussing a problem with a "reapxg.mid", a file which
 * I still have, and how it issues an MSB=0 with a program change on ch 9, 
 * thus turning it into a melodic channel.  The strange thing is, this doesn't
 * happen on XG hardware, nor on the XG softsynth.  It continues to play as a
 * normal drum.  The author of the midi file obviously intended it to be
 * drumset 16 too.  The original fix was to detect LSB == -1, then break so
 * as to not set it to a melodic channel.  I'm guessing that this somehow got
 * mutated into checking for 127 instead, and the current FIXME is related to
 * the original hack from Sept 1999.  The Sept 5th email discusses patches
 * being applied to version 2.5.1 to get XG drums to work properly, and a
 * Sept 7th email to someone else discusses the fixes being part of the
 * latest 2.6.0-beta3.  A September 23rd email to Masanao Izumo specifically
 * mentions the LSB == -1 hack (and reapxg.mid not playing "correctly"
 * anymore), as well as new changes in 2.6.0 that broke a lot of other XG
 * files (XG drum support was extremely buggy in 1999 and we were still trying
 * to figure out how to initialize things to reproduce hardware behavior).  An
 * October 5th email says that 2.5.1 was correct, 2.6.0 had very broken XG
 * drum changes, and 2.6.1 still has problems.  Further discussions ensued
 * over what was "correct": to follow the XG spec, or to reproduce
 * "features" / bugs in the hardware.  I can't find the rest of the
 * discussions, but I think it ended with us agreeing to just follow the spec
 * and not try to reproduce the hardware strangeness.  I don't know how the
 * current FIXME wound up the way it is now.  I'm still going to guess it is
 * related to the old reapxg.mid hack.
 *
 * Now that reset_midi() initializes channel[ch].bank_lsb to 0 instead of -1,
 * checking for LSB == -1 won't do anything anymore, so changing the above
 * FIXME to the original == -1 won't do any good.  It is best to just #if 0
 * it out and leave it here as a reminder that there is at least one XG
 * hardware / softsynth "bug" that is not reproduced by timidity at the
 * moment.
 *
 * If the current FIXME actually reproduces some other XG hadware bug that
 * I don't know about, then it may have a valid purpose.  I just don't know
 * what that purpose is at the moment.  Perhaps someone else does?  I still
 * have src going back to 2.10.4, and the FIXME comment was already there by
 * then.  I don't see any entries in the Changelog that could explain it
 * either.  If someone has src from 2.5.1 through 2.10.3 and wants to
 * investigate this further, go for it :)
