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

Log Message:
- delay processing unblocked threads until after locks are resolved:
  without the blocked/unblocked upcall ordering, an interrupted blocked
  upcall might put the blocked thread on the intqueue because it needs
  to be continued.  With the delayed processing, we avoid putting such a
  thread twice on the runqueue.
- fix putting a thread on the intqueue when it needs to be continued
  after it blocked.

Also check return value when returning a single stack.
