    ucom - Hack unref to fix infinite 1-second wait loop.
    
    * ucom depended on the .tsw_* switch to decomission ports, which we do
      not use currently.  This was preventing the ucom from being properly
      dereferenced and resulted in an infinite 1-second wait loop on close.
    
    * Move the unref elsewhere to hopefully solve the problem.
