are your two different users reading and writing it at the
same time? if so, problems are to be expected. you
need to either

1) set up locking manually, there are some functions
   in the fcntl module to do that, or

2) use gdbm for the shelf object (gdbm does locking itself): copy the
   DbfilenameShelf class from shelve.py and change "anydbm" to "gdbm".
