You're not missing anything, I was.  I was sticking to the
event-handling stuff already done in SKS and I know nothing about how
cleanly O'Caml lets you use threads and combine the two models.  If it's
easy and clean, then my oversight was ... glaring.

None of the current membership has any kind of locking against
concurrent updates -- how much is needed, with O'Caml, and how much
locking done automatically?

I don't quite know what you mean by "automatically", but there are threads, mutexes and condition variables, all in easy reach.
