A kernel debugger in Python: drgn

I wasn't aware of pykdump (and I couldn't get it to run despite my best efforts). It does look similar. As Jeff commented below, he's also been working on another similar tool, crash-python. Clearly, there's a need for this sort of thing and we haven't done a great job of publicizing our efforts, which is part of the reason I presented it at LSF/MM.
