Comment (by SimonKing):
Commit's up. Changes: The iteration guard is now used on all internal
iterations. So, it should now be impossible that garbage collection
changes the length of a hash bucket while we iterate over the bucket.
I could not test yet whether the addition of iteration guards has a
noticeable effect on the performance. Can you test whether the new commit
fixes the crash for you?
