Comment (by SimonKing):
I have updated the patch again. Tests pass on bsd.math.
The difference between enterid(...,0) and enterid(...,1) is that the
former does not allocate memory for `currRingHdl.data.uring`, while the
latter does. Hence, using `enterid(..., 0)`, one avoids the useless call
to `rDelete`.
Apply trac_13447-sanitise_ring_refcount.patch
