Is writing plugins for the new TinyMCE documented somewhere?

And... enrolment is a bit more complicated that you're hoping it is. As courses can have multiple enrolment plugins, there is another layer of tables. So some JOINs are required.

Surely that would act like an upgrade. Granted, one may not notice.

I think that it's *possible* to set the default auto increment starting value in MySQL to something other than one. That would apply to all Moodle tables, though (i.e. user ids would also start at something strange).

Other than that, then yes it's odd.

I'm not sure I understand your question. A process "asks for" a lock. If it's already locked it exits. Otherwise, it runs and then clears the lock.

The problem comes when the process fails and doesn't clear the lock. Locks have a lifetime but the default is 24 hours...
