 =head2 CHILD PROCESS WATCHERS
 
 You can also listen for the status of a child process specified by the
-C<pid> argument. The watcher will only trigger once. This works by
-installing a signal handler for C<SIGCHLD>.
+C<pid> argument (or any child if the pid argument is 0). The watcher will
+trigger as often as status change for the child are received. This works
+by installing a signal handler for C<SIGCHLD>. The callback will be called with
+the pid and exit status (as returned by waitpid).
 
 Example: wait for pid 1333

 The known classes so far are:

+   AnyEvent::Impl::EV        based on EV (an interface to libev, also best choice).

    AnyEvent::Impl::Perl      pure-perl implementation, inefficient.
