 presence is undefined and you cannot rely on them. Portable AnyEvent
 callbacks cannot use arguments passed to time watcher callbacks.
 
-The timer callback will be invoked at most once: if you want a repeating
-timer you have to create a new watcher (this is a limitation by both Tk
-and Glib).
+The callback will normally be invoked once only. If you specify another
+parameter, C<interval>, as a positive number, then the callback will be
+invoked regularly at that interval (in fractional seconds) after the first

+The callback will be rescheduled before invoking the callback, but no
