[issue46726] Thread spuriously marked dead after interrupting a join call

The PR you submitted doesn't work, unfortunately. It essentially reintroduces issue 45274. If this line:

    if locked := lock.acquire(block, timeout):

gets interrupted between the acquire and the assignment, locked is still False. That's rare, but so is an interruption between the acquire and the release, which is the original form of issue 45274.
