This is what I'm trying to do, indeed. I'm trying convince myself that
erlang way is worth further investigation. I've been Java/J2EE
developer for years now and my mind is used to OO and shared memory
concepts. In my case it is really hard to change well trained mind to
start thinking in completely new way. It's really fascinating and
beautiful process, though.

This is why I ask those questions i.e. quad CPU question. I want to
get practical proof the erlang apprach works. I just need the
explanation and please don't laugh at me :D

Regards,
Tom
