"vi"-ing a constantly updated file

Hi,

A bit of a dumb question here. Sorry folks.

Suppose I have this file which is being updated at irregular intervals (a few seconds, a few minutes, who knows) by a background process.

I 'vi' this file with the intention of editing it, so it opens up a temp copy as the usual /tmp/720cwhatever

Now suppose, whilst I have this file opened, its updated several times by the background process.

I make my changes, save-quit.

What happens to the updates that were made by the background process during the time I had the file opened?

How do I mitigate this?
(unfortunately, stopping the background process is not an option).

The file is fairly big also (about 40Mb) so it takes vi a few seconds to load it up, save to it etc.....

Unix is ksh.
OS is SunOS.

Hope you guys can help! - thanks in advance!
