I have a manual test that demonstrates the problem when using pepper postmessage, which executes script via WebBindings to create & dispatch a MessageEvent. Without this patch, the passed string gets garbled about 1 in ~3000-6000 times. With this patch it succeeds. I haven't been able to reproduce it elsewhere. I can add that test to the bug so anybody who can build a trusted pepper plugin can reproduce, but I'd much rather have a decent automated test in WebKit. I'm still a total n00b in WebKit/V8 land.

A couple of questions:
(1) Does this look like I'm on the right track?
(2) Do you have a suggestion as to how to test this? I'm looking at LayoutTests/fast/events right now, but it would seem easier to test directly on top of the C++, but I'm not sure where to put such a test.
