Maybe this could be done, albeit in a rather primitive way:
Separate standalones communicating with each other?
Cheers,

Bidirectional message queue.
Send messages to a thread in 'send' style.
My initial idea would be that when you send a message you could do so
indicating it should be run it it's own thread (or in an existing
thread that you know the name of). By default each object (button,
field, card etc) would have a mutex that you must hold to update it's
attributes or to run any of its handlers (this would be acquired
automatically). It would be possible to do finer grained locking if
the programmer took the trouble to code it. The automatic acquisition
of locks would be dependent on some global property (that might also
be used to permit the creation of threads in the first place) so there
would be no overhead for non-threaded stacks.
I think something like that might work, however I wonder what the right
way would be to make this fit into the Revolution way of things and to
ward off potential problems.
It might start off simple, perhaps between sort of between a thread and
a process in which a library script is used to create a thread and
messages (like with send) are sent back and forth. The shared resources
might be added based on that. Same with accessing objects.
That is far from being able to access anything the home thread could, so
folks might think that too weak.
