 Not sure and maybe the patch is only for benchmarking / testing out
 things, but wouldn't the ''de''compression part in `torgzip.c` also need
 changing?

 {{{
 302     switch (inflate(stream, complete_only ? Z_FINISH : Z_SYNC_FLUSH))
 }}}

 and

 {{{
 477     err = inflate(&state->stream, finish ? Z_FINISH : Z_SYNC_FLUSH);
 }}}

 or am I mistaken?
