Log Message
-----------
If the nodelock can not be obtained then the worker will keep retrying instead
of exiting.  Bug # 132 discussses issues where slon can't restart because
of a duplicate node lock.  The watchdog instance of slon can kill the worker
child and restart it.  The issue is that postgresql backend for the old
worker might still be around when the new worker tries to get the nodelock.

Prior to this patch we only had one shot at this, now we will keep retrying
until a user decides to kill this process or the other one goes away
