By defining a private variable "StatusProc", you are causing
the routine id of "StatusProc" to be -1. This turns off the 
(frequent) callback to StatusProc(), so things work much better. 
I think I mentioned already that things worked much better 
when that callback was turned off.

Yes. The video capture option doesn't consume much time.
You can't even tell it's runnning. A time-shared 
task writes frames of data to disk when there's nothing else to do. 
A profile_time on Language War shows that about 90% of the time it's just
sitting in the scheduler waiting for the clock to advance so
it can run the next task.

I hope so. There are a few places where I lose a tiny bit of
performance in order to work around a Watcom bug.

Yes, I'll probably do that.
I want to make sure everything is rock solid before
I start inserting small optimizations.
