------- Additional Comments from Andrew Wilson <atwilson at chromium.org>
This test is intended to check for race conditions when cloning a port while
posting messages to it from another thread.

To ensure the case is adequately tested, we have some checks in place to make
sure that clones are actually happening in parallel with messages being posted.
The previous threshold (1000 clones) was chosen entirely arbitrarily, and
turned out to be a order of magnitude too strict for some platforms (like
Chromium). So I've loosened the requirement.

I also relaxed a timeout that fires only in the test failure case, again
because the latency involved in cross-process messaging in Chromium was causing
it to be flaky.
