Why don't you make the gen pool size a function of the number of CPUs on
the system and have it all work automagically?

Burdening the user with yet another cmdline switch is a bad idea. We
have way too many as it is.

This stuff should work out-of-the-box, without user intervention if
possible. And it is possible in this case.

Thx.
