These unexpected{Abort,Success,Complete}Callbacks do not seem to be referenced?

[Dai Mikurube (NOT FULLTIME), 2011/08/30 08:07:55]

Thanks.  I forgot to remove them.  I was using code from IndexedDB's
browser_tests as the first step.

Not for fileapi?

[Dai Mikurube (NOT FULLTIME), 2011/08/30 08:07:55]

Done.

I think in the new fileapi tests we're not using these shouldBe methods; am I
correct?  If so let's remove these replicated methods.

[Dai Mikurube (NOT FULLTIME), 2011/08/30 08:07:55]

Done.
