This works to some extent; the output in the TaskWindow doesn't get
loused up.  However, I need to pass some non-constant arguments to
the Absolute app, which means Filer_Run won't work directly.  I
presume this means I'd have to construct an Obey file in a writable
directory, then Filer_Run that.  Is there any easier way?
