   Whatever M$ does ... well ....... always seems
   to be FUCKED somehow.

   Anyway, pipes are VERY useful. Anybody getting into 'C',
   esp multi-threaded/process, needs to get very familiar
   with them. Even in 'C' they're still kinda awkward
   alas. Somebody had The Idea, but nobody seems to have
   made it smooth and consistent across multiple languages
   and systems.

   My old server experiments, each child returned stats
   back to the root parent while it was running. Under
   certain conditions the parent would do things - maybe
   terminate the child or connection or do a timer
   process. Did work up to a fairly compact UDP bi-di
   pre-threaded server. Never found a great use for it,
   but it was fun and maybe someday .......
