<h3>Log Message</h3>
<pre>http/tests/xmlhttprequest/event-listener-gc.html is flaky
https://bugs.webkit.org/show_bug.cgi?id=33342
Reviewed by Darin Adler.
Instead of using a zero delay timer, which can be legitimately delayed for dozens
of milliseconds, perform the collection in a second load event handler. GC code
has changed so much that I cannot confirm that the test still verifies the fix,
however we collect after returning for the function and unwinding the stack, so it should.
Also, clear the JS variable for a good measure.
