Much more could be done here, but at least now we have *some* automated test coverage of that mechanism. In particular this tests the writable-CTE case reported by Phil Sorber. In passing, remove isolationtester's arbitrary restriction on the number of steps in a permutation list. I used this so that a single spec file could be used to run several related test scenarios, but there are other possible reasons to want a step series that's not exactly a permutation. Improve documentation and fix a couple other nits as well.
