Description Jonathan Bedard 2022-11-01 10:35:33 PDT

multiprocessing.Queue spawns a thread, which is used to support features we don't use. Newer versions of Python define a "SimpleQueue" which has the set of features we need, but Python 3.9 doesn't support 'timeout' and 'block' on the 'get()' function, which we need. These are relatively simple to implement ourselves, though, which is what fixing this bug will entail.
