Threading or similar in LiveCode

Hi Rod:

I'm don't use Python but if you're referring to threading as in
multithreading -- running multiple threads simultaneously -- LiveCode
doesn't have this.  One way you can *kind of* simulate threading is using
the send command:  send "xyz" to button 5 in 20 millisecs .  This doesn't
accomplish true multithreading, but in some cases allows near simultaneous
processing of multiple messages, if the code to be executed isn't too time
consuming or blocking.  Another method could be to run a completely separate
LiveCode process and allow the two to exchange data/messages.

Other folks may have additional suggestions.
