   I don't get a hang but I do get a crash.  It looks like some `read_table` cleanup work is still happening after the method returns.  Then, during shutdown, it tries to close the file and that tries to grab the GIL but python is already shutdown so this crashes.  This is one of the things I'm hoping to eventually cleanup with the new scanner which :crossed_fingers: will make it in 12.0.0.
   
   Do you get a hang if you sleep for a few seconds after the read call before you exit the process?
