Using any kind of potentially-blocking synchronization primitive from __del__ or weakref callback is indeed a bug waiting for happen.  I agree non-trivial cases can be hard to debug, especially when people don't expect that kind of cause.

It would be ok to submit a patch solving this issue using C code IMHO.  Note the maxsize argument complicates things even though most uses of Queue don't use maxsize.

Of course, the general issue isn't only about Queue: other synchronization primitives are widely used.  See https://github.com/tornadoweb/tornado/pull/1876 for an example.
