Don't know.  I was asking the same question.  Lyle's comments above
were addressing the context of doing a direct volume dump from the
file server without going through the volserver (i.e. not using vos
dump or backup dump).  I was just wondering out loud if in the
presence of the same competing accesses this is a non-issue when
doing the dump "the normal way".
