bug report is actually wrong, reality is far more bizarre and broken
than that).

On the negative side, the interface is I<bizarre>, with the event polling
On the negative side, the interface is I<bizarre> - so bizarre that
even sun itself gets it wrong in their code examples: The event polling
function sometimes returning events to the caller even though an error
occured, but with no indication whether it has done so or not (yes, it's
even documented that way) - deadly for edge-triggered interfaces, but
fortunately libev seems to be able to work around it.
even documented that way) - deadly for edge-triggered interfaces where
you absolutely have to know whether an event occured or not because you
have to re-arm the watcher.
Fortunately libev seems to be able to work around these idiocies.
This backend maps C<EV_READ> and C<EV_WRITE> in the same way as
C<EVBACKEND_POLL>.
