Summary A test that hangs at cleanup stage confuses webkitpy hugely

fast/forms/form-associated-element-crash3.html is a test that's known to hang after it dumps results (see bug 122130). Having a test like this confuses WebKitTestRunner a lot. 1. There is output saying that last line of output was not a newline, and there is a bug. 2. The next test is incorrectly reported as crashing. $ run-webkit-tests -2 --no-retry-failures -v fast/forms --child-processes=1 ... [150/810] fast/forms/form-associated-element-crash3.html passed Last character read from DRT stdout line was not a newline! This indicates either a NRWT or DRT bug. [151/810] fast/forms/form-associated-element-removal.html failed (WebProcess crashed [pid=44775])

This is probably essentially the same as bug 118602. It's not clear that there's a good way to fix this given the current way the test harness communicates w/ WTR.

Can we log here?

No, the script doesn't expect any output before the next test begins.
