This is not really true for typical elisp programs -- global variables
(especially buffer-local global variables) are used extremely often,
and in almost every case must be "truly global" (visible in all
threads).

However, if a global variable is let-bound, the let-binding should of
course be thread-local.

My personal feeling is that it may be easiest to simply move to a
deep-binding system for elisp (and ideally use lexical-binding for
local variables), but such a change may be a lot of work given the
myriad special varieties of variable bindings (buffer-local etc).
