Avoid throwing interrupted exception in JoinThread 

I saw a stacktrace when exiting sbtn on windows due to an interrupted
exception being thrown during thread joining. We only want to throw this
exception if we didn't successfully join the thread. I also noticed that
we would try to join the thread forever. There was supposed to be a
timelimit so that we would eventually stop blocking even if we were
unable to join the thread. The limit was set but not respected.
