SIngle process, single CPU, not very recent machine. (600MHz crusoe based
machine so) That machine wasn't hardware accelerated though, so was only able
to handle several dozen sprites before slowing down. The slowdown was due to
the hardware not being able to keep up with pygame's drawing requests though
rather than the framework.

I'll note them as things worth doing - they look reasonable and interesting
benchmarks. (I can think of a few modifications I might make though. For
example in 3 you say "fastest". I might have that as a 3b. 3a could be
"simplest to use/read" or "most likely to pick". Obviously there's a good
chance that's not the fastest. (Could be optimised to be under the hood
I suppose, but that wouldn't be the point of the test)

Nope, just plain old python (I'm now using a 1.6Ghz centrino machine
though). My mixing function is particularly naive as well. To me that says
more about python than my code. I did consider using pyrex to wrap (or
write) an optimised version, but there didn't seem to be any need for
last week (Though for a non-prototype something faster would be
nice :).
I'll save responding the linda things until I have a chance to read in detail
what you've written. It sounds very promising though - having multiple
approaches to different styles of concurrency that work nicely with each
other safely is always a positive thing IMO.
Thanks for the suggestions and best regards,
Michael.
