Hi Christian,
Thanks for experimenting with a different solution.

173 // New traps in the MDO may have been added since we copied the
174 // data (concurrent deoptimizations before we acquired
175 // extra_data_lock above) or can be removed (a safepoint may occur
176 // in the prepare_metadata call above) as we translate the copy:
177 // update the copy as we go.
Can the above still happen?
I see you dropped the memcpy so I suppose no?
Roland.
