Since it is unreproducble, the only chance is to track it down on a machine
where it is indeed reproducible.

The purpose is not writing into the signal pipe when there is already
a byte in there, avoiding both extra syscalls and overflowing the pipe
itself (remember that that was the main reason for netscaoe 4 freezing
all the time. this cannot happen with libev for other reasons, but its a
sensible optimisation).
