+   know output is done.  So the forking process must close its copy of the
+   file descriptor.  BUT: if the output of the filter is not an internal
+   pipe but this program's output, then we don't want it closed when the

+   the program converts (with a whole new chain of filters).

+   To prevent the progam output file from getting closed, we pass a
+   duplicate of it to spawnFilters() and keep the original open.
