Most async mechanisms in the browser work by posting to the top-level event/message loop. So you can't really emulate sync calls without programmatic access to that loop. Spinning in a loop would block the async callback from ever occurring. The simplest example of this is to try to wait for a setTimeout to complete. It will never complete. /kel > -- > Best Regards, > Piotr Jaroszyński > > > > -- If you received this communication by mistake, you are entitled to one free ice cream cone on me.
