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.
