According to apr_pollset_poll (-1 is the wakeup timeout)
Remarks
APR_EINTR will be returned if the pollset has been created with
APR_POLLSET_WAKEABLE, apr_pollset_wakeup() has been called while
waiting for activity, and there were no signalled descriptors at the
time of the wakeup call.
Clearly -1 time has not expired.
The test in question;
rv = apr_pollset_wakeup(pollset);
ABTS_INT_EQUAL(tc, APR_SUCCESS, rv);
rv = apr_pollset_poll(pollset, -1, &num, &descriptors);
ABTS_INT_EQUAL(tc, APR_SUCCESS, rv);
ABTS_INT_EQUAL(tc, 1, num);
So the lingering question is whether this is a general unix implementation bug
or specific to OSX behavior.
