I believe I read somewhere the max # of processes per thread on OS X is 256, although you may want to check that. I think I recall reading it somewhere in the Multithreading Guide.

It is 2500 on Leopard, per a recent discussion on the Java-Dev mailing list.

As in that discussion, I'll reiterate my (somewhat informed) opinion that getting anywhere close to that limit is a recipe for a performance disaster.

Don't worry, I'm not REALLY planning on doing anything like that! :) This was more of a 'what-if' exercise, just to see if any bugs turn up. And, as it turns out, one did.
