-The C<$state> argument is a reference to an initially empty hash,
-which the application can use as it sees fit, to store its own
-connection-relation information. For example, an application might
-use C<$state-E<gt>{last}> to keep a record of which was the last record
-retrieved from the associated connection. The pod module itself does
-not use the state hash at all, and applications are also welcome to
-ignore it if they do not need it.
+The C<$arg> argument could be anything at all - it is whatever the
+application code passed into C<wait()>. For example, it could be
+a reference to a hash indexed by the host string of the connections to
+yield some per-connection state information.
+An application might use such information
