I have a local repository of built packages linked to my sbuild
instances. Everytime a build is successful, the repository indexes are
updated. In case of multiple builds, it could happen newer concurrent
builds start to update apt cache just in the middle of a
apt-ftparchive run, resulting in a "hash sum mismatch" error.

I would like to implement a simple locking mechanism using plain files
(it's definitely not the best approach, I welcome better ideas ;). I
acquire the lock in the chroot-setup and I should manage the removal
of the lock if something goes wrong in whatever stage. With the
current status, if sbuild fails in apt-get-update the lock is never
deleted because no commands are triggered.
