Hmmm...  Your comment there seems to be an indicator that you don't
have a lot of experience with real-time, performance-centric apps.
Consider my previously listed examples of video rendering and
programatic effects in real-time. You need to have a lot of stuff in
threads being worked on, and as Walter described, using a signal
rather than serialization is the clear choice.  Or, consider Patrick's
case where you have massive amounts of audio being run through a DSP--
it just doesn't make sense to serialize a intricate, high level object
when you could otherwise just hand it off via a single sync step.
Walter and Paul really get what's being said here, so that should be
an indicator to take a step back for a moment and ease up a bit...
C'mon, man--we're all on the same side here!  :^)
