2 or more processes on the write end of the same pipe

[Skaperen]

i got it working using os.pipe() and os.fork(). i omitted any effort to track processes for os.wait()s because i am leaving them all running until i kill them all and exit. every try with subprocess and multiprocessing did not succeed (exceptions kept happening in child processes). but i wasn't trying it the way you did.

these child processes all run various ping commands. the parent reads the pipe to get all ping return events. next i will add code to accumulate stats in real time with output to files and/or stdout. one planned example is a one minute average doing sliding window and comparing loss to multiple IPs in parallel.
