Ah yes, sorry, I should have been clearer in my earlier remarks. The new vector-sorting code can be considerably slower than sorting a list of the same length, if the comparison predicate is expensive. But existing code (which just sorts lists) should not be affected by this, as the list-sorting code is the same as before.

Anyway, I'm looking into a fix for all this.
