             This time simply fires at the wallclock time $at and doesn't
             repeat. It will not adjust when a time jump occurs, that is, if
             it is to be run at January 1st 2011 then it will run when the
             system time reaches or surpasses this time.
-        *   non-repeating interval timer ($interval > 0, $reschedule_cb = 0)
+        *   repeating interval timer ($interval > 0, $reschedule_cb = 0)
             In this mode the watcher will always be scheduled to time out at
             the next "$at + N * $interval" time (for some integer N) and
             then repeat, regardless of any time jumps.
         managed automatically.
         The "embed_ns" variant doesn't start (activate) the newly created
         watcher.
+   ASYNC WATCHERS - how to wake up another event loop
+    Async watchers are provided by EV, but have little use in perl directly,
+    as perl neither supports threads nor direct access to signal handlers or
+    other contexts where they could be of value.
+    It is, however, possible to use them from the XS level.
+    Please see the libev documentation for further details.
 PERL SIGNALS
     While Perl signal handling (%SIG) is not affected by EV, the behaviour
     with EV is as the same as any other C library: Perl-signals will only be
     handled when Perl runs, which means your signal handler might be invoked
     only the next time an event callback is invoked.
