yes, I have a final pending patch which didn't make it to the branch 
before the merge.  It changes the behaviour of atomic_flag on targets 
with no compare_and_swap.  I *think* it will resolve your problem.

I've attached the early version of the patch which you can try. Its 
missing a documentation change I was going to add tomorrow before 
submitting, but we can see if it resolves your problem.  Give it a shot 
and let me know.
