I have a sneaking feeling that what you are going to come up with is a
multi-megabyte patch to convert CurrentMemoryContext into a non-global,
which will require changing the parameter list of damn near every
routine in the backend.

Personally I will vote for rejecting such a patch, as it will uglify the
code (and break nearly all existing user-written extension functions)
far more than is justified by what it accomplishes: exactly zero, in
terms of near-term usefulness.

I think what's more interesting to discuss at this stage is the
considerations I alluded to before: what are we going to do with the
caches and other potentially-sharable datastructures? Without a
credible design for those issues, there is no point in sweating the
small-but-annoying stuff.
