You will have race conditions, if your are running several processes.

I would suggest to "JEP" a non destructive bind. That is, if the 
resource is already in use, the bind would fail.

But since a server can be hours with undetected failed connections, 
perhaps a more sensible approach could be to bind with a random 
resource, send a stanza to the demanded resource, and if the resource is 
offline or not answers in X seconds, rebind to it.
