Now *that* is interesting. I assume filehandle 130 here is about the
self-pipe, since it's keyed at read and write events (POLLIN|POLLOUT).
But here revents says POLLOUT which means ready for writing, but this
triggers an attempt to read...
I need to think about this, and rework the self-pipe design!
