OK, I'll just re-emphasise one point. A minimal bit of testing suggests that
^ and $ will always cause it to hang. My guess is that, although the timeout
code works on the connection, it will never ever have anything to match
against because these conditions cannot occur in a stream (there is no
equivalent to End-Of-String) so it will keep going back and looking and not
finding anything to match that $.
