[haiku-commits] r33681 - haiku/trunk/src/system/libroot/os

Author: mmlr
Date: 2009-10-20 21:05:35 +0200 (Tue, 20 Oct 2009)
New Revision: 33681
Changeset: http://dev.haiku-os.org/changeset/33681/haiku

Modified:
   haiku/trunk/src/system/libroot/os/locks.cpp
Log:
Add small but very important missing detail. Before blocking it didn't set the
wait status and therefore would return directly without actually blocking.
