Suspecting the following patch caused the failures. Disabling the tests as the patch was landed more than 1 hour ago.
tkent@, PTAL. Thanks!

My CL must be unrelated to the test.
Assign to the test author.

This is in fact a bug in the test. It combines chunks it receives using Array.prototype.join, which by default comma separates the chunks. Instead it should be passing the empty string to join() to make sure no random commas end up in the output.
Thanks Marijn for identifying the problem.  I'll make a CL.  Might be a bit delayed due to TPAC.
