Do you think this script should lock the repo while reading it's content?
Otherwise there is a chance it reads a package or db file while it's being
modified. We might even loose all previous data which would cause the script
to reread all packages on the next run.
The problem with all this might be that we end up with a bunch of scripts and
operations which block each other.
ATM, if we move a lot of packages, db-move will lock and unlock the repo for
each of them. If one of our cronjobs gets lucky and catches the lock between
two packages the move script will fail and we'll end up with an inconsistent
repo. I guess one step to solve this is this (hard to read) patch
And maybe we should even have read and write locks.
