This test case can easily grow the heap to fill my entire 8GB physical
addressing space with both ghc 7.0.3 and ghc 7.4.1. This despite the fact
that the original vectors themselves are only 8MB in size and only
supposedly non-copying calls are being made. Commenting out either of the
prints at the end returns things to sanity. I'm unsure of whether this
should be
Presumably the case could be simplified a bit, but this was my first cut
at paring it down.
