> It broke the test because the test hand feeds appends and syncs with when
> they should throw exceptions. In the test we manufactured the case where an
> append fails and we then asserted the following sync would fail.
> Problem was that we expected the failure to be a dropped snapshot failure
> because fail of sync is a catastrophic event... but our hand feeding actually
> reproduced the case where a sync goes into the damaged file... before it had
> rolled... which is no longer a catastrophic event... we just catch and move
> on.
> The attached patch just removes check for dropped snapshot and that abort was
> called.
