Too many d's for the day. :) I agree with Benjamin, that we
can't rely on the 16-bits being reserved forever.

I have a question about the lower 3 bits OTOH. The minimal
GC allocation size is >= 8 bytes, right? I.e. if we set the
lower 3 bits to 0b111, and the pointer points to a 4 byte
structure, it will still be recognized as an internal pointer
due to the overallocation.
