This part I do not understand.  Emacs locks a file (and creates
autosave files) only if a buffer is visiting a file and you modify
the buffer.  There is no lock for files if a buffer is visiting the
file without modifying it.  So for BBDB that means: only if you make
changes to the database (i.e., modify the buffer visiting your
~/.bbdb) emacs locks this file.

You could let bbdb-after-change-hook run bbdb-save.  But as I said,
I'd consider this dangerous, in particular if you believe you do not
make changes to your database in the first place.
