DeprecationWarning: setDaemon() is deprecated, set the daemon attribute instead

[abigailfox]

setDaemon was deprecated in Python 3.10 (https://docs.python.org/3/library/threading.html#threading.Thread.setDaemon) in favor of directly setting the daemon attribute. Investigating to see when Python started supporting setting the attribute directly to see if setDaemon can be safely replaced without compatibility issues
