[Pythonmac-SIG] os.pipe()

A pipe is an operating system construct, and one that MacOS (9 or earlier) 
doesn't have, so that's what MacPython doesn't have it.

If you haven't seen pipes before they're probably best visualised as a serial 
line, but going between two processes on the same machine in stead of between 
two machines.

Pipes can sometimes be simulated by letting the first process write a file, 
and then reading it by the second process after the first one terminates. 
Another (often better) option is to use sockets.
