Modified Files:
	src/lib/libpthread: pthread_sa.c

Log Message:
* Recycle upcall stacks as soon as possible rather than waiting to
  accumulate half of the total number. There are too many ways for
  the SA subsystem to deadlock waiting for stacks that userland has no
  reason to recycle.

* Consolidate switchto handling in pthread_resolve_locks().

* Add code to re-chain the preempting parents of switchtos.

* Tweak debuglog output in a couple of cases.
