I agree, a crappy interface, why on earth would you do it
that way. The details of the locking should be buried in
the stream attribute routines that you write. If you want
the locking mechanism to be general, you could even make
an extended stream type that had the necessary lock field,
but most likely it would be perfectly convenient to just
use a single global lock.

I really don't see a significant problem here, it seems a
straightforward programming excercise, but most certainly
you don't want the client calling the stream routine to
have to do the locking, and of course (reread my messages)
I never suggested such a thing -- that was your suggestion!
