Committed By:   nathanw
Date:           Wed Aug  1 23:37:37 UTC 2001

Modified Files:
        basesrc/lib/libpthread [nathanw_sa]: pthread_sa.c

Log Message:
Add some debugging framework I've been using a lot (can easily be
compiled out).

Bugfix 1: In the new_preempt case, it is possible for victim and
switchto to point to the same thing. Don't but one thread on the
runqueue twice when this happens.

Bugfix 2 (along with changes to pthread_switch.S and pthread_int.h):
Restore the useful ucontext of a thread that is preempted on the
original stack in pthread__locked_switch().
