NetworkDaemon allows several 'threading models' to be pluged into it. 
In particular, MultiThreader() (daemontest -p) implements a Boss/Worker
model with a pool of threads, similar to Apache's processes to avoid the
creation overhead.  The main thread acts as the boss, while the threads
on the pool are the workers.  If your program takes things from the net,
NetworkDaemon is a good choice.  Else, it's a good starting point,
IMHO.  You could use the same threading strategies (they should be
fairly generic, I'm open to changes), but with different input source.

I understand your problem, I've gone thru a lot of headaches to try to
minimize OS dependant stuff to osdep.hpp for the HP/UX port.  Once it's
working we'll see how we can make it. neater.
