Put this next to the original so the diff is  more obvious?

[jvoung (off chromium), 2015/03/28 01:18:34]

Done.

Naively, I would have expected this tests to do some sort of smoke test
postMessage "ping" to check the nexe is alive afterwards...

[jvoung (off chromium), 2015/03/28 01:18:34]

Good point.

I could make a separate pexe, or I could enhance the simple.cc test (though I
guess that would cascade to about 3 other test html/js).
