CVS commit: src/lib/libpthread

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Wed Apr  1 10:13:24 UTC 2009

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

Log Message:
Fix the comparision function used by the red-black tree global thread list
implementation:
-don't return a difference, this can overflow
-don't try to substract typed pointers which don't belong to the
 same object, this gives undefined results

This fixes instabilities of programs which use more than a handful
of threads, eg spuriously failing pthread_join().
