The goal is to eventually get rid of all the _hot stuff and always take the lock from the top level, this would allow us to do more register read/write batching and that would amortize the cost of the locking overall.
Of course when I say 'get rid of the hot stuff', I mean get rid of the 'hot' _naming_ and not the behavior, since the goal is for all register accessors to be 'hot' aka unlocked.
