    Same as my other question earlier, if an error occurs during start 
operation, viewVersion could potentially be -1 still.  Does this handle that 
behavior correctly?  We do this try/finally pattern in a lot of places, as 
Bruce stated, maybe we could combine into a common method (there are some cases 
where this may not be possible)
