I'd prefer blink::Heap::collectAllGarbage(), (which calls Heap::collectGarbage()
multiple times to ensure that everything is gone).

Acknowledged.

And there is another case crash that I did not make any change in this CL for it
(I think it is not exactly a issue but it's a noise) : 
the test case CheckAndMarkPointer will trigger a ASSERT in 
ThreadState::copyStackUntilSafePointScope
ASSERT(slotCount < 1024); // Catch potential performance issues.

     blink::ThreadState::detachMainThread();
     blink::Heap::shutdown();
     return result;
 }
