This patch also eliminates the thundering-herd problem of the manual-reset event, which (theoretically) wakes up all threads waiting on. Now the behavior of the CV's should be the same on Unix and win32 platforms. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@551965 13f79535-47bb-0310-9956-ffa450edef68
