The idea was to execute all thread on every frame, and having a yield() native 
function somewhere in the script that would stop execution for the current 
frame. This, in addition to lambda abstraction, allows a very clean 
implementation of all current wait condition and much more.

Pseudo code below:

def wait(cond:lambda)
{
        while (cond())
                yield()
}

But surely Marvelous can help you on this.

Have a nice day,

Steph
