btw, from this follows as well, that there is no need in supporting a
bunch of remappable oops.
It really should be only a single remappable oop all the times.
So, instead of push/pop, it can be set/get. And this single value
should be set to nil, or smallint when primitive returns.
But i'm really doubt that it needed at all.
At the stage when primitive generating new object(s), which can be
subject of remapping , a primitive failure is quite unlikely, so
arguments on stack can be overidden.
