I think there is agreement that we're not going to change
cancel_before_shmem_exit's restriction to only allow LIFO popping.
So we should improve its comment to explain why. The other thing
that seems legitimately on-the-table for this CF entry is whether
we should change cancel_before_shmem_exit to complain, rather than
silently do nothing, if it fails to pop the stack. Bharath's
last patchset proposed to add an elog(DEBUG3) complaint, which
seems to me to be just about entirely useless. I'd make it an
ERROR, or maybe an Assert.
