Add failing large HTML file test.

Running this test yields a bunch of `(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.` warnings, and then a stack overflow.

Happy to work on solving it, but I'm inexperienced with debugging gnarly stacks of node streams, so progress might be slow...
