This seems neater. It doesn't have any significant effect because: The poller fd wouldn't be emptied by time_occurs. It would only be woken by time_occurs as a result of an ao completing, or by libxl__egc_ao_cleanup_1_baton. But ...1_baton won't be called in between (for one thing, this would violate the rule of not still having the active caller when ...1_baton is called). While discussing this patch, I noticed that there is a possibility (in libxl in general) that poller_put might be called on a woken poller. It would probably be sensible at some point to make poller_get empty the pipe, at least if the pipe_nonempty flag is set.
