VirtualFile.hasBeenModified() useful?

[bill.burke]

Do you think a hasBeenModified() method would be useful on VirtualFile?

It would return true if lastModified() does not equal the timestamp of the file when the virtualfilehandler was allocated, OR, the last time hasBeenMOdified() was invoked. Could be used in DeploymentScanners.

I think this is too much of a constraint on the implementation to support.
