OK.  This looks, then, like a situation which is dependant on the local
environment.  With xterms off a central server I can see the problems.  
With a bunch of networked PCs (what we have here) it may be less of a 
difficulty.

I would not like to have the executables be more "powerful," so localizing
locks would be a better solution.  Perhaps this could eventually be a 
configuration option.  Of course, there likely are more important things 
to worry about.  :^)

Thanks for your time.

Adios,
