When you say "unstable" you mean that tests fail? DRT crashes? Mostly DRT seems to hang as if it's blocking on locks. I haven't attempted to debug it yet, but it seems very reproducible at least on my 8-core Mac Pro. sample DumpRenderTree should give us some information as to what's going wrong.

You may be hitting the same issue that I hit when I did something like this.

Note that https://bugs.webkit.org/show_bug.cgi?id=36899 may also fix this, as might https://bugs.webkit.org/show_bug.cgi?id=33153 . I am not currently working on this, nor do I expect to be in the near future, so I am disclaiming ownership in case someone else wants to take a look. This should be fixed as of r79062. |
