An idea on multithreading implementation

Oh I just thought of what really set me thinking about this. Let's say you wanted a command to check every 10 seconds for the state of a folder, and then have your stack ready to do other things meanwhile. You cannot do that. A handler has to be running to make the call to check status. 

I suppose you can have a recursive function that calls itself in time, but can LiveCode be doing other things at the same time? I dunno.
