Correct. About the only time you would want simultaneous access from multiple OS's to the same file system is either via a network-based file system (such as NFS) or via a "clustered" file system (such as OCFS or GFS), both of which are designed to prevent file system corruption if properly implemented. I didn't mean to imply that the file-locking was a mistake or something "bad" in this situation.
