Ah, yes. Good point; that would work too.

That's why I didn't initially mention it.

I don't presently see any simple solution for the general case, except
to note that these are traditional problems of parallelism and there's
no reason we can't implement traditional solutions such as semaphores,
locks, queues, mailboxes and other kinds of inter-process messages as
Zigzag cells. If anything it might make them more visual and hence
perhaps easier to understand.
