Yes it would, you're just approaching it the wrong way.  You'd count
the number of entries rather than getting it via pointer subtraction.

On relatively recent systems it is possible to use .hidden in order
to allow __JCR_LIST__ to be non-static yet not exported.  You may be
able to rely on HAVE_GAS_HIDDEN for this, but I am not sure.

Anyway, eliminating synchronizations is a Good Thing.
