sysdiagnose output

I've seen this a few times in the recent nightly builds. Maybe starting 2-3 days ago. I'll have the new Safari Inspector open, and do something like reload a page or type in a new URL. I may have had the timeline recording, but I'm not sure; I don't have consistent repro steps. Anyway, Webkit starts beachballing and gobbling up memory like crazy. I watched it go up to 5.5GB "Real Memory" in Activity Monitor in about 30 seconds.

I ran a sysdiagnose, which took forever. sysdiagnose gave me the following output, which makes me think it missed the spindump stuff. I took a sample of the process in Activity Monitor when it was done, but I'm not sure if it will be relevant. At that point, the process was using <1% CPU, but the web page still hadn't loaded. (It never did, actually. I force-quit the process eventually.)
