Hmmm... I think that maybe there should be a flag to allow two 
services with the same name to co-exist rather than one to disallow it?  
EXCL is an obvious flag choice for the way things are now

I think having two with the same name is the more rare case and the way it is
sure confused me :).

Wouldn't the current situation be a race when calling caps_drop and caps_hold
to increment and decrement the reference counts?
