We need to find a more permanent solution for this. This could take one of two forms: We say that what mysqli is currently doing is incorrect, and it can't rely on skipif being run before the test. This seems a bit annoying for these tests, because code would have to be duplicated between the skipif and the test. The alternative is to have an opt-out for caching. For example, we could print a nocache result from skipif.

I've implemented the nocache tag in 4d43cbe and 0074a1d, so this should hopefully be resolved now.

Thanks, Nikita.
