For some reason I thought we had talked about this. Give me queries
and an id block to return results back to a client and we can have
parallel query. I favor reserving four bytes in the header for this.
We might have an issue with transaction context depending on the
engine (I need to look into this still).
You need multiple threads per session, and probably more
synchronization on the session level. This is probably doable?
But I think that it is better to implement serial execution of
statements before concurrent execution. Arbitrary execution order may
sometimes cause transaction deadlocks.
Uh, more often it will lead to wrong answers.
