+=head1 FORK
+
+Most of the "improved" event delivering mechanisms of modern operating
+systems have quite a few problems with fork(2) (to put it bluntly: it is
+not supported and usually destructive). Libev makes it possible to work
+around this by having a function that recreates the kernel state after
+fork in the child.
+
+On non-win32 platforms, this module requires the pthread_atfork
+functionality to do this automatically for you. This function is quite
+buggy on most BSDs, though, so YMMV. The overhead for this is quite
+negligible, because everything the function currently does is set a flag
+that is checked only when the event loop gets used the next time, so when
+you do fork but not use EV, the overhead is minimal.
+
+On win32, there is no notion of fork so all this doesn't apply, of course.
