One of the things @rnewman's considered is how to allow canceling or interrupting Mentat queries. He concludes that the best way to achieve this is to farm queries to separate threads. That's because SQLite doesn't allow to cancel running queries, so the way to achieve this is to just kill the thread and let SQLite's atomic commit mechanism handle clean-up, etc.

This ticket tracks experimenting with this approach, working through whatever communciation/synchronization primitives are necessary, whatever thread pooling is desired, etc.
