Beggin' to differ with you, Captain.  I showed you the errors from mv.  I
showed you the process from ps.  I told you it kept copying the files. 
I'm sure we agree my process wasn't killed, as that term is commonly
understood.  ;-)

The mv process died; I got back control as soon as I pressed ^C.  It was
evidently the exec'ed child that was invulnerable.  Several files had been
copied, so it wouldn't seem to be a question of timing.  

Is it possible that the target filesystem (smbfs) is significant?  

I thought the behavior I witnessed was expected.  Since it's not, could
someone suggest a more precise test to isolate the problem?  Because it
obviously *can* happen.
