This tells us that preservation of files/directories is not
guaranteed between program /invocations/.  It does not tell us
anything about the guarantees /during/ program execution, which
is the bit that's important to us.

In the case of an X session such as gnome-session, the process will
run for the lifetime of the session.  In the absence of aggressive
cleaning, it's reasonable to expect the contents to be present for
the duration of the session.
