That's right. The problem is file locking - some systems (VMS, Apollo)
had good or adequate file locking across machine boundaries so we could
handle remote drives. When I last looked at NFS (which was not recent)
it did not have a reliable way of discovering whether a file had been
opened by another process if the file was on a network drive. Windows
seems to have the same problem. If a database is opened by two different
servers which are unknown to each other, the servers will corrupt the
database.
