[rlarocque, 2014/06/20 20:03:35]

Testing races is nonesense.  I've replaced it with a test that syncs changes
from client 0 to client 1, then from client 1 to client 0.  This is equivalent
to one of the possible race scenarios from this test.

[Nicolas Zea, 2014/07/09 18:52:15]

Why do we disable the verifier in these tests?

[rlarocque, 2014/07/09 19:01:17]

In this test, I think it's out of habit.  It's based on "Race", which couldn't
use the verifier because its outcome was not deterministic.  I'll try turning it
back on.

In the test below (UnsyncableBooleanPref), it's disabled because we expect some
of the preferences won't match.

sync-affecting preferences, then makes sure that these preferences don't match.
