That's too drastic.  My suggestion would be to include the file name
in the prompt for the master file in case the buffer is not visible.
The following patch accomplishes this:

                 (list TeX-default-extension)
                 'path))

Drawbacks: The prompt may become very long and the file name is not
only included in the example with preview-latex you mentioned but also
when an existing file with a shared master is opened because
`switch-to-buffer' is the last thing executed by `find-file', i.e. the
buffer will not be displayed when the question is asked.  Maybe
somebody knows a better test?
