AFAIK we watch this description only when we're inside
"wait_reading_process_output and accept-process-output".  If we're
inside `read-from-minibuffer` then we're not inside
"wait_reading_process_output and accept-process-output" (and
vice-versa), so I don't think there should be much trouble (at least for
my understanding of POSIX file descriptors, which is admittedly somewhat
limited; for Windows, I have no idea).
