Module Name: src
Committed By: drochner
Date: Thu Apr 2 12:58:45 UTC 2009
Modified Files:
src/regress/lib/libpthread: Makefile
Added Files:
src/regress/lib/libpthread/find: Makefile findthreads.c findthreads.sh
Log Message:
add a test which exercises libpthread's ability to remember the
threads which were created, doing some random mallocs in between
so that threads are not equidistant in the address space
(bug fixed in libpthread/pthread.c rev. 1.109)
