* local locks in low-level index sub-objects seem to allow us to omit session-context lock in CConcSession::GenerateHitStrings() -- yay! ; test script reports Amdahl P > 99% for N=4 and simple @-queries; P ~ 80% for CAB-expanded queries

+ local locks in m_pIndexator sub-objects (CStringIndexator, CConcXml, CIndexSetForQueryingStage via new ddcLockable base-class (simple single-lock object) -- simple parallel @-queries seem to work now

+ client-threads work in progress: clone term expanders (b/c curl handles can't be shared)
- tests with @-queries often show 100% expected responses
- expected responses as low as 29% for -n 32 -i 128 : something is still foul
