  Log:
  Redo the sigio locking.
  
  Turn the sigio sx into a mutex.
  
  Sigio lock is really only needed to protect interrupts from dereferencing
  the sigio pointer in an object when the sigio itself is being destroyed.
  
  In order to do this in the most unintrusive manner change pgsigio's
  sigio * argument into a **, that way we can lock internally to the
  function.
