It would be nice to be able to avoid pre-emption at I/O points also,
ensuring that turns on the event loop run atomically to completion,
and any IO wait happens on the next turn.

I guess I can discover any pre-emption at I/O points easily with a
dynamic-wind handler or custom loop and go and rewrite them.
