svn commit: r1795952 - in /apr/apr/branches/1.6.x: locks/unix/misc.c locks/unix/proc_mutex.c locks/unix/thread_mutex.c test/testlock.c

Author: wrowe

New Revision: 1795952

URL: http://svn.apache.org/viewvc?rev=1795952&view=rev
Log:
Revert r1790105;

Add in our own pthread_mutex_timedlock impl for those OSs, like
osx/macos that don't have it. Be a bit more generous in the test
