Thanks for this.  I should have been more specific and say that I was
trying to write ruby code in C to then launch the forks....so I really
mean to duplicate the ruby code to be ruby code ...in C....

Kaspar,

Passenger does it, but using ruby.  Mongrel doesn't install yet in
1.9, although I need to still go through the online code...I'm going
to guess they do it in ruby as well.

Any chance you could point me to actual code that does this?  I looked
at eventmachine too, but I'm not good enough to figure out what I
need, which is kinda why I'm here.

Again, thanks for any tips.

Mike B.
