This implies that any time OS X implicitly terminates an app, it potentially
leaves all the files that were open in an inconsistent state, inaccessible by
anything else. This flies in the face of a half century of OS design. When
people get errors trying to open file A from app X because file A was open in
app Y three days ago, you don't want to be the guy working the call center.
