AFAIU that's not a "problem", but a design decision.  If only one of
your processes accesses the database, then code which takes care of
concurrency is unneeded overhead (and will maybe introduce new bugs).
If you have more than one process, there are locks.

Well, it's Arthur's code, but my take on this is that the major
advantage of Rucksack over almost all other Lisp persistence packages
is that it is pure Lisp.  Introducing a foreign library just for this
task seems like a very bad idea to me.
