In addition, select() is exactly what the linked recipe uses to
implement non-blocking I/O for subprocesses on non-Windows platforms.

I agree the actual use cases need to be better articulated in any RFE
that is actually posted, but a cleanly encapsulated approach to
non-blocking communication with subprocesses over stdin/out/err
certainly sounds like something that could reasonably be added to the
subprocess module.
