-Date: Thu, 12 Mar 2009 20:56:59 +0000
-Subject: [PATCH 01/39] linuxthreads fixes from Will Newton (will.newton AT gmail.com):
- * share Sys V semaphores in order to get appropriate SEM_UNDO semantics.
- * correct guardaddr in pthread_free() for TLS case
- * move spinlock unlocking before restart()
- * When exit was called from a signal handler, the restart
-   from the manager processing the exit request instead restarted the thread
-   in pthread_cond_timedwait.
-   (see http://sources.redhat.com/ml/libc-ports/2006-05/msg00000.html)
