Is that something you can share?  I have some dual-core Intel h/w I'd
like to try this on.  The xsc3 core doesn't implement all of the v6 ISA
(v5te only), but does have the standard set of ARMv6 memory barriers.

[ In theory the two xsc3 cores in this CPU aren't cache coherent but
  I'd like to try it anyway. ]
