struct child_wait *
child_wait_new_with_pid(pid_t pid, child_wait_callback_t *callback,
			void *context);

This would make it easy. That code is already written, but it's not in
Dovecot's CVS yet. It would be useful also in dovecot-auth. Originally I
was thinking about using the code to replace the waitpid() calls in
master, but that change got a bit complex so I forgot about it then.

Added.
