Well, see, dpkg 1.8 in incoming no longer calls an external gzip binary(note:
this is a configure option).  It is linked to zlib statically.  This gives a
small speedup.

In dpkg cvs(what will be 1.9), dpkg no longer calls an external md5sum(it also
doesn't fork for it, which it still does for the gzip above).  This isn't as
bad, because it already had it's own internal md5sum binary, I just moved the
code into the internal library it uses.
