I still don't understand.

I don't see when such memory can ever be collected in the java sense.
It seems to me that it must always be explicitly freed according to
the usual C rules.  So if one of these `int' handles represents
C-style memory, then you have to pass in the original value in order
to free the memory.

Mapping int->pointer is a problem in the presence of pointer
arithmetic.  But this could be addressed by putting object size
information into the lookaside table.
