(some extra debug added locally). When this happens there are entries in the cooker log which look like:

Comment 1 Richard Purdie 2022-09-02 19:53:43 UTC 
I have a reproducer:

    self.client().ping()
    self.client().loop.run_until_complete(self.client().client.close())
    os.chdir("/")
    self.client().ping()

i.e. trigger a close() inside the client code, chdir and then trigger a reconnect.

This is because the path variable is cached in connect_unix connect_sock's context but the cwd is changed and the path is no longer relevant.
