Make listen() retry

Browse Source 
Pacemaker requires this in order to operate.  Multiple fencing requests
will not come from a single host, however, it is possible that multiple
instances of fence_xvm will need to run at approximately the same time.

e.g. one 'status' or 'hostlist', one fencing action.
