updates
hacked up to debug why we're not getting
signals on redhat etc.
take out debug logs.
overhauled the main loop. (BIGLOOP) in Loop.cpp.
sigtimedwait() was cutting it, it was queueing up too
many DUPLICATE signals and overflowing the rt signal queue.
now gb has its own real-time signal queueing logic that
just sets the bit of the FDs that need attention.
i think threaded reads/writes are better now too but
the performance graph is broken so i need to fix that first.
the threads page looks good though. overhaul this hopefully
is a massive and stable performance improvement.
show process IDs on the stats page now.
use scp not rcp for 'gb installgb' because it doesn't
work on default redhat systems.
added dotgdbinit file for gdb
