I need to update existing tests and add new tests.  Factoring out the CommitQueueTask object should allow for much better testing of this logic.

This patch is absolutely fantastic.

This block is kinda confusing.  I think it may need some comments to annotate what its doing.

We could also have a _validate_and_land() command which it called instead, and reverse the logic.  But it's kinda nice having the ifs be always for the failure cases.

As far as I can tell this is "right" :)
