Yes, and I use checksum almost exclusively.  I could, of course, use
'IfFileExists(foo.lock)' to define a class (or whatever the function
name is; I forget) and then only update if that class is not defined.
The problem is that I'd need to do such a thing for EVERY file, which
would not only be tedious to implement, it wouldn't be possible for
recursive directory copies.  Now that I think about it, however, it
might be doable to implement a host-wide lock with minimal changes to my
existing configuration.

Right.  And my opinion, and what I am asking Mark to consider, is that a
simple tool and a few changes in the existing code to check for and
report the locks would be better than increasing the complexity of
current configurations.

Yeah, I know it can be done like that, but my wish is for something
