svn commit: r1897549 - /apr/apr/trunk/include/apr_poll.h
Author: ylavic
Date: Thu Jan 27 14:20:36 2022
New Revision: 1897549
URL: http://svn.apache.org/viewvc?rev=1897549&view=rev
Log:
poll: Follow up to r1897521: Clarify what APR_POLLEXCL means.
This is to avoid the thundering herd issue when multiple threads/processes
poll on the same descriptor (usually listening/to-be-accept()ed descriptors).
