webgl/1.0.2/conformance/more/functions/copyTexImage2DBadArgs.html fails frequently on Yosemite Debug WK1 tests due to the expected results being truncated.

It seems there might be a race condition in the run-webkit-tests test harness that is causing this.

It's strange that it only affects this single test on Yosemite Debug WK1, though.

According to the Flakiness Dashboard, this started with:

Test run: <https://build.webkit.org/builders/Apple%20Yosemite%20Debug%20WK1%20(Tests)/builds/5818>

WebKit trunk r186270:  <http://trac.webkit.org/r186270>

Looks like this only happens on bot183, every time.

In other words, it's probably file system cache corruption, and we should reboot.
