If anyone wants an interim solution, I have something like this working
already (0.65.1 through 0.99.0). It uses delay(), and works well (and
transparently), except when you run out of memory when loading a
dataset, then it turns to custard (but if you're out of memory, you need
to restart anyway).

Contact me if you need more information.

Hope this helps,
