    32 // mDocWasToBeDestroyed - Gets set when "someone" tries to unload the document

    33 //   while we were prparing to Print. This typically happens if a user starts

    34 //   to print while a page is still loading. If they start printing and pause

    35 //   at the print dialog and then the page comes in, we then abort printing

    36 //   because the document is no longer stable.
