It looks like the acceptor reads its port number from the default
section of the configuration file. If so, you'd be able to have
any number of sessions defined for that acceptor as long as they 
connect to the same accept port.

I can see how that might be a problem in C++. :-) Sometimes that's done
intentionally in Java programs. For example, applications can be isolated
from each other (including "singletons") by using separate class loaders 
for each application.
