If I'm reading the source correctly, a driver can't send an unsigned
32-bit value back to Erlang.  It cannot send an arbitrary bignum,
either.  Is the former (or both) possible to include in R9 at this
late date?

For what it's worth, it doesn't appear possible to have the driver
create a reference and send that back to Erlang, either.
