Connections in progress are now explicitely written to the mknotifyd.log. This makes it easier to spot ongoning, unsucessful connection attempts.

Furthermore, in case of polling errors a timeout of 1s was added. This prevents the mknotifyd from using 100% CPU if an error appears and the polling returns immediately.
