Yes it is. That's a result of two things: 1) The people who invented pipes were *very* smart (but not smart enough to invent stderr at the same time :-). 2) Pipes use a dead simple concurrency model. It isn't even as powerful as CSP. No shared memory. No synchronization primitives. Data flows in one direction, and one direction only. Basically, each element of a pipe can be programmed ignoring concurrency. It doesn't get much simpler than that. <mike -- Mike Meyer <[EMAIL PROTECTED]> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. -- http://mail.python.org/mailman/listinfo/python-list
