The network layer has been eliminated as the problem.  I just captured a trace
where the second chunked encoding fell on a packet boundary (started in a new
packet), but the page rendered incorrectly.

I could not reproduce this on a nightly, but easily reproduced it on production
Safari (the same version listed in Comment #0).

The bug must lie somewhere in the parser/tokenizer, but it looks like it's been
fixed in WebKit ToT.
