As you can see, it is turned off by default. And, it only works for
NFS shares(Unix flavors(including Darwin), but not Windows). And,
this does not suggest that it would be possible for multiple Firebird
servers to use the same database file, without ANY negative effects.
And, having the database file on a remote system in relations to where
the Firebird server is running, does have its drawbacks and would have
to be used with caution.
