PTest failure is unrelated to this patch.
I'll fix the test tomorrow

Looks like this caused a test failure:

Test should now be fine.

This test file was running promise tests.
But the promise was not returned to tstharness so the test file was done before all promises were resolved. This was fixed in bug 161389.

This was noticeable here as we are starting to do some console logging stuff.
Sometimes the logs happened before the test was done sometimes after, hence the flakiness.

I can reupload this patch to resubmit it to EWS bots if that helps.

Yes, we should definitely store this bool before moving it.  We shouldn't land code that uses a variable we have WTFMoved from.

I saw that already in WebKit code base, maybe this should be in WebKit coding style.
I can do that change in that patch, although this will make a tad more difficult to review all the changes.
