Even future additional splits are precluded because it might break someones dotted import (i.e. not a single function can be moved between those files -- once in unittest.utils, alway in unittest.utils).

Can Python 2.7 pickles containing unittest classes be unpickled using
2.6 or earlier? Even if nobody uses the new names for imports, I
believe they implicitly end up included in any pickles involving
affected classes (I seem to recall we've been bitten by that before
when moving things around).

Cheers,
Nick.
