Richard,
This is a great explanation. Are Flash apps subject to the browers'
"fairly extensive event loops" as well, or has Adobe overcome that
somehow? It is interesting to see how the two products match up.

As I suspected from both Richard's and Sarah's findings that the
calculational parts (calculating the positions and velocities of
all the balls and determining the new positions and velocities
after collisions) run very well in Safari. But the motion of the
balls is very stuttered. It runs at full speed, that is it takes
the same time to execute one "shot" but the motion of the balls is
herky-jerky.
My guess is this is related to the browser's event loop.
When running in a standalone, there's only the Rev engine's event
loop and those of whatever other apps and OS components are running.
But when running in the browser you have all of that plus the
browser's own fairly extensive event loop.
I suspect with all of the events browsers need to trap, dispatch,
and handle, what you're seeing is just a natural by-product of
running inside the browser.
