I think you may be up to the whim of the system in any case. In UNIX and
probably Linux systems, data in pipes tends to remain in RAM from when it it
placed into the queue and when the consuming process reads it out. There is
a limit (once it was something like 1024 bytes) on how much the producing
process would write until it blocked, and it would unblock only when the
consuming process emptied it out.
