You must call this function after forking if and only if you want to -use the event library in both processes. If you just fork+exec, you don't -have to call it.

The function itself is quite fast and it's usually not a problem to call
it just in case after a fork. To make this easy, the function will fit in
quite nicely into a call to pthread_atfork
