Hm OK, these commits were meant to address that precisely..
It looks like SLES has some special epoll_wait() implementation that
can return before the timeout. Could you printf the t2 - t1 diff in
the justsleep() test after apr_pollset_poll()? It could be interesting
to know if it's almost 200ms or close to zero (the latter could mean
epoll_wait() does not block if there is no fd in the pollset, which is
the case in this test).

Yann.
