Even if I call Lwt_unix.fork applications sometimes segfault when libev is used with OCaml 4.02.2.
libev needs some special functions called to work correctly after a fork:

There is also something wrong with using OpenSSL and fork with OCaml 4.02.2 , everything fine on 4.02.1 and 4.01.0.

I'll try to create a testcase to show this.

Turns out this was a bug in OCaml 4.02.2, the patch from here fixes the problem: http://caml.inria.fr/mantis/view.php?id=6919
