  Log:
  Fix a crash on access to TAP's owning thread.  The owning thread can go away
  with the descriptor still open, for example if the opening process forks
  into a background daemon and the foreground process exits.
  
  Use the SIGIO mechanic to record the owning thread so we can detect if
  the process goes away.
