AFAIK, one usual method is to make sure that all "yields" are always on the
bottom of the stack so you don't need to keep and store stack for each
script. This of course rules out real preemptiveness. But... how do you
handle that anyway? Don't you ever get problems with one script being
interrupted in the middle of modifying some object and another one accessing
that same object in a half-valid state? And having scripts running on a
different thread? Do you use some synchronizations when accessing other
subsystems from scripts?
