  10-15 seconds after trussing thunderbird:

    $ truss -t!all -u libX11: -p $(pgrep thunderbird-bin)

  and then releasing it:

    ...
    <ctrl-c>
    $

  thunderbird dies (seemingly reproducibly) on a SIGTRAP in
  tdb_event_create:

    > ::status

  It appears we aren't properly deinstrumenting the target when we
  detach.
