I nagged Andres off-list and he opined that it might be better to
reorder it a bit so that ProcessSyncRequests() comes after almost
everything else, so that if we ever teach more things to offload their
fsync work it'll be in the right order.  I reordered it like that; now
only CheckPointTwoPhase() comes later, based on the comment that
accompanies it.  In any case, we can always reconsider the ordering of
this function in later commits as required.  Pushed like that.
