Here 'tis. This passes check-world, unlike v1 (mea culpa for not
checking that). I also cleaned up the variant expected-files,
so it's now no worse than HEAD as far as failures in serializable
mode go.

I played a bit more with insert-conflict-specconflict.spec, too.
It now seems proof against delays inserted anywhere in the
lock-acquiring subroutines.
