Thanks. Yes, this is supposed to be review by JIT person. On the other hand, if JIT person has better solution, GCv5 would like to use. Anyway we hope write barrier is to be functioning in the DRLVM soon.

It would probably be best if a JIT person committed this patch. Maybe Stephan Mishura? If its not committed soon, bug me and I will do it.
