Subject svn commit: r1666618 - /httpd/httpd/trunk/server/mpm/event/event.c

Author: ylavic

New Revision: 1666618

URL: http://svn.apache.org/r1666618
Log:
mpm_event: follow up to r1666468.
We only need one compare function for add semantic with apr_skiplist_insert()
and unique timers (pointers). It also should work with apr_skiplist_remove()
and apr_skiplist_find(), be they used some day.
