Who Owns An Application?

I'm going to state this as a general problem, rather than discuss my particular situation.

Suppose A is an application that owns data, D. Further, another AppleScripted application, B, is accessing and modifying data D via A. When B is finished, it quits. Usually, B runs only a few seconds, but it could run for a few tens of seconds if there is lots of data to process.

The problem is that B does not own A. Application A has a user interface and the user can operate A at any time, even while B is running. The user can quit A or close a window, causing B to error if its running. I have done this by accident and while I didn't lose any data, D, I think this is a dangerous situation.

The solution is for application B to acquire total ownership of application A until B is finished. I don't know of any way to do this, however.

One possible work-around in B is to
tell application "A" to display dialog ...
This puts a dialog in front of A which prevents the user from clicking in A ... A just beeps. Unfortunately, (1) the dialog has a button which the user CAN click and (2) the dialog has a button which the user MUST click.

Application B could hide application A, then show it when finished, but this looks really ugly to the user to have windows suddenly disappear. And the user can go around this by clicking A's Dock icon.

Is there any way for application B to establish exclusive ownership of application A, excluding all user interaction with A, until application B is finished, thus protecting data D?
