Here is another patch to uemacs.4.0a, MicroEmacs 4.0.

It allows multiple users to create locks in the same directory at the
same time.  Without the patch, the first user to edit a file in a
directory creates an _xlk directory that only he can add files to,
preventing other users from creating locks.

The comments are self-explanatory, and may be removed if you wish.
