Looks that way to me; and I think it considerably safer than using any
hard-wired address. My current feeling is that the problem stems from
waiting too long to reattach to shared memory, and that we ought to do
that as soon as we can read the shmem address info from the temp file.
Just had a thought ... is it possible that this problem was introduced
by the recent changes to pass backend variables in shared memory instead
of in a temp file? ISTM fairly possible that mapping that memory is
going to interfere with where we need to map the main shared memory
block. I see that it gets unmapped after being read, but maybe the
damage is already done.
