This patch turns a lot of test into the streamed mode.  While it's
great that streaming mode is tested, we should add new tests for it
rather than failing to keep tests for the non-streamed mode.  I suggest
that we add two versions of each test, one for each mode.  Maybe the way
to do that is to create some subroutine that can be called twice.
