While this is true, this is not the problem that is preventing Office
applications from opening in-use files in read-only mode.  The problem
is that a shared lock for a particular byte-range cannot be obtained in
AFS due to the fact that the file servers do not yet support byte range
lock allocations.

We are all looking forward to the day that the byte-range lock
implementation you have been working on can be merged into the tree.
