This is an issue i have run into with the dpkg and dpkg-deb applets, in
.deb's there are two .tar.gz inside an ar archive, if you read too much
much for the first tar.gz youve read past next ar header, and possibly
into the next .tar.gz.

(busybox supports .tar.bz2 inside deb's buts its non-standard)

hmm, i need to do some testing to verify its current behaviour.
