Well if you use fork() you will have address space handling overhead on any platform, it just wont hurt you on Unix generally. If you are using threads then you can run 5000 threads in one application happily (although there are sound technical reasons its a dumb thing to do for efficiency) > Oh, one last thing: > There seems to be a belief that L390 is a port of meta code instead of > natively compiled code.

In the sense that their may be VM under it and complex microcode I guess that is to a small extent true. Linux on 390 is native 390 code however.
