CVS commit: src/lib/libpthread

[Christian Limpach <cl%netbsd.org@localhost>]

Module Name:    src
Committed By:   cl
Date:           Mon Nov 17 22:59:00 UTC 2003

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.
