Do we need to provide a workaround for this issue as specified in the URL above?

I think this issue is not easily reproduced in many normal applications which bind only a few times in their lifetime. And this issue will be resolved as soon as Mustang is released. I don't think we need to fix it actively if there's no specific real use case.

I won't provide a wordaround for this issue due to no demand.
