AudioRendererAlgorithm, AudioRendererImpl, and SeekableBuffer all have a sad coupling around capacity. Ideally exposing a frames() variable should be enough for SeekableAudioBuffer, AudioRendererAlgorithm or AudioRendererImpl can then maintain the proper watermarks.

I feel I should elaborate on this. The gtest EXPECT_EQ() macro __is the only ones__ where we do yoda comparisons since its API actually wants the expected value first so that it can print out very pretty and well-formatted text. All other macros ([D]CHECK_XX(), EXPECT_LT, EXPECT_NE) don't discriminate, so we like to have them not be all yoda-y. For reference, here's the most recent discussion we had on the topic: http://goto.google.com/videostack-yoda
I should also clarify that my iterator comments are if you switch to deque as scherkus suggested, list is safe.
