> DRLEM profile collectors code to access method profiles is not thread safe.
> All 3 profile collectors: entry-backedge, edge and value profilers, do not use locks in getMethodProfile routine.
> However the map that is used to keep method<->profile mapping can be modified from a separate thread when new profile is created.
