Getting back to the idea about parallelizing on a per-test base and not per-layer: The ZODB currently runs only unit tests (which became a true layer in zope.testing/trunk) but takes about XX minutes on one of my machines (4 core XEON, 3.2 GHz). I'd suggest that the general principle of splitting up the runs over multiple parallel processes should happen in a way that if you have X total tests and N parallel processes, we should have roughly X/N tests run in parallel. We could use layers as a hint to create subprocesses, but should split up layers if they are too large to fit the X/N rule (maybe with a margin of a few percent to avoid splits for single or few tests).
