 there are a lot of shoddy libraries and programs (glib's threadpool for
 example) that can't properly initialise their signal masks.

-This flag's behaviour will become the default in future versions of libev.
+The current implementation only tries to use a \f(CW\*(C`timerfd\*(C'\fR when the first
