Immediates have one of the the two lowermost bits set; anything else can 
be a pointer to the heap.  This is because on all platforms where ruby 
runs, pointers to VALUE are aligned on a multiple of 4 bytes.

If on your platform you are seeing most pointers starting with 0xC, then 
that's likely where your heap is located, but that may not be true on 
another platform.

There is unused space with the 5 lowermost bits set to 10010, giving 27 
bits to play with, though this might break some optimizations that 
assume anything with the LSB set to 0x2 is true.
