// mDocWasToBeDestroyed - Gets set when "someone" tries to unload the document
// while we were prparing to Print. This typically happens if a user starts
// to print while a page is still loading. If they start printing and pause
// at the print dialog and then the page comes in, we then abort printing
// because the document is no longer stable.
