Just to reinforce the concept one more time (at the risk of beating a
dead horse), descriptors don't have buffers and thus don't need to be
flushed; *streams* have buffers and need to be flushed; closing a stream
also flushes it.  It's impolite at best to muck about with a stream's
descriptor without at least asking its permission first.  And it's
highly impolite to take a descriptor away (by closing it) from a stream
that's still using it.
