I’ve wrapped the permablocking (.connect() permablocks if a host does not exist rather than failing or timing out) StreamPeerTCP.connect() in a method of my class to call with Thread. I then check in _process() to watch elapsed connect time and it gets to my timeout value (say 30 seconds). How do I kill the thread (that is still caught in .connect()'s block)?
