Randall,
These "interlocks", at least as far as renaming goes, might in fact be
restricted to Windows Explorer. It seems possible (from the limited
testing that I did) to rename a file that is locked, or move it to another
directory on the same volume. If I may venture a guess, Windows Explorer
is unable to move a locked file because it implements move as copy/delete
to avoid special-casing for same-volume moves.
I've had a similar problem with cvs trying to remove lock directories on
samba drives. While not necessarily related (I had no infinite loops,
just a "permission denied" on remove), I was able to rename or even move
the directory (while it was considered locked), as long as it was on the
same volume.
