I have not tested this case, maybe it works. What does not work is if
an application is opening a file and another application is opening a
sqlite db in the same folder. The GRASS sqlite driver should print
reasonable error messages, so it should be easy to test

According to the sqlite documentation, that should be fail-safe.
