What thread does JavaScript code called from Flash execute on?

Question

Hi,

As far as I understand, all JavaScript code is event-driven and executes on a single browser thread.

However, I have some JavaScript functions that are called from within a SWF object sitting on the same page. Is this code run in the same manner as regular JS code, or is it on some separate Flash thread?

If it is on a separate thread, can I use setTimeout() to get it to run on the JS events thread? e.g.:

function calledFromFlash() {
    setTimeout(doActualWork, 0);
}

function doActualWork() {
    // blah blah blah
}

Thanks, Karthik

It's still on the same thread. However, for most practical purposes if you have such a long-running JavaScript that you're worried your "main" task might block the call from setTimeout, you should consider revisiting your underlying approach.
