How can you guarantee that the Berkeley DB files
are accessed only by local processes?

For example, if you are running an indexing utility
remotely, could that corrupt the files? My guess is no,
since probably remote read-0only access is okay.
But I'm not sure.

Similarly, sometimes it's more convenient to run backup
utilities remotely. Problematic? Probably cannot guarantee
that the database snapshot is consistent - but then that
is the usual problem with all databases, you can't use
filesystem backups on thedm without quiescing the database
processes that may have data in memory.

Again, my guess is overall that remote read-only access
is okay, although consistency cannot be guaranteed.
