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.
