I was poking fun at you on IRC for this exact reason:

<rostedt> poor Vince, I keep sending him new patches. "No, don't test this patch, now test this one. Oh wait, try this one instead"
* peterz sees Vince thinking: "stop... sending.. me.. damn... patches... already... !!!11!"
<rostedt> or at least, "Let me finish this test before I cancel it again for another damn patch"
<rostedt> then he's probably doing "I'm not going to run any tests now, until I wait a while to see if there's a new patch to test"

 :-)

Anyway, I would say wait a bit while we sort this out. At least we have
a strong idea of what the bug is. Now we need to agree on the solution.

Vince, you have been really terrific in helping us figure out what was
wrong. I don't want to waste your time until we can all agree on what
the proper fix is. When we do, it would be great if you can test it.

But for now, have a great weekend and thanks for all your hard work in
narrowing down this issue.
