dang!

Committed a limit of 200000.

A couple of observations:

* I don't think you could do this with an early 2.4 kernel on i386 because of 
eating up kernel memory with LDTs, assuming APR thinks it can support threads. 
Not sure about current kernels from popular distros.

* Should I assume you tried worker but it uses too much CPU?  If so, is it a 
small percentage more or really really bad?

Thanks,
Greg
