	I assume we will not stop here sync for some connection that
was normally expired in master but was delayed in backup. TCP sync
starts for EST state, so I think it will hit the above case.

You mean that we could end up ignoring a sync msg that we shouldn't ignore?

	Yes, that was my worry but I don't see how the code
can fail, so it looks fine to me.

Ok, cool. I'll do more tests and probably post this by next week.

Thanks Julian.

Regards,
Marcelo
