[ email moved to win32 list.]

They have only a few regression tests failing, so we are very far along.

The message you are seeing looks like code that assumes that a child can
map to the same shared memory address as the postmaster.  We haven't
seen that fail for anyone before, but it is an assumption we weren't
sure about.  Of course this is all a guess.
