da626d1bc6 Because of the requirement to make popped objects dead in a timely fashion, we can only implement lightweight pops to an address in the buffer. in particular we can't support pending pops, which means that there's no need for the fields in the allocation point that support pending pops.

b06795251e Fix scanning/walking for snc: 
Record which segments are free and don't walk them (objects in these segments are dead).
If a buffered segment has a pending pop, don't scan or walk objects beyond the address that's going to be popped to (these objects are also dead).
Don't try to do a lightweight pop to an address that's not in the segment attached to the buffer -- the segment being popped to (and any other segments on the stack in between) are now dead, and the only way to mark them as being dead is to do a heavyweight pop.

* Turn off the spare memory on the MVFF pool so that it returns freed memory to the arena immediately.
* Allocate something in the MV pool initially so that the span and block pools have some capacity.
* Stop the test if there isn't room in the MVFF to allocate 2 big blocks.
* Change the test success criterion so that it passes on 64-bit.
