So it's really bcs->bcp() that may have changed, and hence the 
aligned_bcp calculated from that. Seems ok.

I hadn't realized we have safepoint issues for data other than oops. 
Makes we wonder how can we detect/prevent this kind of issue. Also makes 
me wonder how we might better flag data that isn't safe across a 
safepoint, and methods that might lead to a safepoint?
