Yeah, t0106 is a tough one given the EM interface.

Btw, has anybody sent a patch to the EM guys to allow this?
(I don't do C++)

That's probably fine.

Fwiw, nowadays my personal take these days is to avoid EM/libev*-style
wrapper library unless they expose (or only have :P) a oneshot interface
(EPOLLONESHOT/EV_ONESHOT).  This is *especially* the case (for me) when
mixing epoll/kqueue with threads.

Standard event-triggered and level-triggered interfaces are both too
confusing to me.  Maybe it's just me, though :x
