Eliminate the overhead of thread creation and destruction.  The usual 
approach is to start the threads in the pool and pass the "Command" 
objects.  The thread then invokes the run() or execute() on the Command.

IIRC this was described in the Active Object pattern (which talks about 
the Command in this context).

This is often used in things like Web servers.
