+The patch is in now.
+
+I readded the wait() and the second fork.
+
+The parameters for the child_init function are swapped in apache 1.3 (!?).
+
+I've been testing with apache 1.3 and 2.0 MPM worker and it works fine.
+
+About locking around the call to fork mod-mono-server, we can do it
+for apache2 if you want, but there's no need for it. The only
+'problem' i've seen so far is that i get this in the logs:
+---
+Error: There's already a server listening on /tmp/mod_mono_server
+---
+
+Some time ago, i made mod-mono-server try to connect to the socket
+before binding so it just exits when it is launched from several
+processes at the same time in a 'there can only be one' fashion. If
+for any reason we get more than 1, only the last one that Bind'ed the
+file will be actually working.
+
+As for the watchdog setup, the easiest approach is to have a script
+that runs mod-mono-server in a loop and restarts it (doing a cleanup
+if needed) when it dies unexpetedly. Then set MonoExecutablePath to
+the path of the script (make it executable ;-) and you're done.
+
+I feel a little bit embarrased for not finding that child_init stuff
+before but at the same time happy for, finally, getting rid of this
+problem in mod_mono. You made my day.
+
+Again, thanks.
