 This works by calling \f(CW\*(C`getpid ()\*(C'\fR on every iteration of the loop,
 and thus this might slow down your event loop if you do a lot of loop
 iterations and little real work, but is usually not noticeable (on my

 The big advantage of this flag is that you can forget about fork (and
 forget about forgetting to tell libev about forking, although you still
