Doh!  That=E2=80=99s a problem.  The GC won=E2=80=99t detect those referenc=
es either,
which can lead to early-deletion problems.

We=E2=80=99ll probably have to disable it.  (According to =E2=80=98file=E2=
=80=99 it=E2=80=99s no a
standard compression format like gzip; maybe raw zlib without gzip
headers?)
