Then perhaps not STDIN of your (child) script, but STDOUT of the parent script (or whatever its corresponding file handle is) may be buffered?

    I believe STDOUT from my parent always flushes (so <STDIN> always works if the parent is working)

    My problem occurs if the parent hangs, because the child process then hangs waiting for <STDIN>

    So I was hoping for a way to be able to timeout waiting for <STDIN>
