I have bad experiences with locking, it always seems to bring more
trouble than it's worth (stale locks, problems with nfs, ...).

We could probably add but I would prefer to keep it as a compile time
option if we do.

I think the place to look would be in libplanner/mrp-project.c, but we
are using libgsf for the file handling so I'm not sure how straight
forward it would be to add locking.
