           Summary: DumpRenderTree relies on unpredictable timing for onload
                    events
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4

Yeah, I'm not too sure about it myself yet, but I've been struggling for hours
with seemingly random test case regressions that shouldn't be caused by my
patch, and this bug seems to be the cause.

Basically, if you introduce a delay into DRT's code, and it doesn't like it,
the RenderTree will be output before javascript requesting text only output can
run, which will obviously make test cases fail. 

I've reproduced this on a clean source tree by simply loading DumpRenderTree up
in a debugger, running it with
LayoutTests/dom/html/level2/html/HTMLBodyElement07.html, and pausing execution
at some point while it runs, and then resuming it. That causes it to
consistently output the full render tree for me, even though that specific test
case requests a text only output.

I won't be able to submit my patch to 5122 until this is fixed :(
