Bummer, I would have thought one advantage of using TLS must surely be memory
protection ? So the only for pg useful usage for TLS seems to be "__declspec(thread)"
and "__declspec(thread) static" (both for stuff that do not need runtime
preinitialization).

Maybe the techniques of electric fence could be used for protecting the shmem
at least a little bit.
