svn commit: r1733774 - /apr/apr/trunk/include/apr.h.in

Author: ylavic
Date: Sat Mar  5 23:14:29 2016
New Revision: 1733774

URL: http://svn.apache.org/viewvc?rev=1733774&view=rev
Log:
Windows' proc_mutex doesn't require require an additional thread_mutex to
synchronize inside the same process, and hence can simply be mapped to a
global_mutex, saving both a double lock and a resource for the latter.
