When you write a patch and the "why do they do it this way, it seems
so silly!" thought comes into your head, I encourage you to review the
extensive git history surrounding this code, notably:
http://projects.archlinux.org/pacman.git/commit/?id=c8beffa7904abe7e0ad01fed6113acf449df15cd

Until you teach bsdtar to not store a new gzip timestamp each time it
creates a package (and thus makes packaging actually produce the same
package every time), this patch totally breaks lessons we learned 2
and a half years ago.
