True, although in many cases one has to interface to legacy C

I'd like to avoid the extra code and CPU cycles if it isn't at all necessary.

You don't need a queue, though; just use your own write function
with a lock.
Hmm... that would certainly work. I suppose it's even more efficient than a
queue in that the first thing
than having to stop the entire program, fix the line, and then run
again and potentially kill a bunch of time getting the program back into the
same state.
Thanks,

This is wrong, because if you know well one language only, you tend to
