Threads are very expensive objects to create so you should always use a 
thread pool for things like this, which allows you to avoid killing 
performance with new Threads if the Java stuff cannot keep up with the 
RPG requests.

You should also consider how you want the system to behave during peaks, 
because it might well be sufficient with e.g. ten threads in the pool 
and anymore than ten requests will just have to wait.
