Step 2: Make a API test, if possible. Prerequisites include getting TestWebKitAPI a Modern API bundle and ... causing the issue to reproduce at all. Going to try this now, but I want to keep it separate from the fix for mergability's sake (most likely going to change bundle loading code). Step 3: Fix a few less obviously bad but still confusing cases of message receivers not being removed before the object is destroyed. Step 4: Add some assertions that catch this and the other cases; Anders and I wrote some nice assertions today that catch all of these things.
