It may be, but I've never understood condition variables properly.
They seem to be semaphores with some additional semantics but it never
made enough sense to me that I felt I could use them with
confidence... the docs never helped. I was raised on semphores, and
that's all I know. :) If you actually understand condition variables
and how to use them, could you kindly explain them to me? I would be
grateful.
