Sorry to waste your time.  Now fixed, I hope.

Having slept on this I wonder if it might be better to always do this
recheck in the event core before making the fd callback.  The current
semantics are a bit of a gotcha.
And this, done.  These 3 patches are entirely different to the last
attempt.

Again, compiled but not tested.

I tested the v2 patches and no longer see the problem. I didn't review them closely, so ATM can only add

Thanks Ian!
