	Although this is true, and it works, you *do* have to wait for scons to initialize and build the DAG before it starts cleaning.  For large builds, this can take awhile.

	Personally, I find it far more convenient and expedient to simply use a VariantDir() and do my cleaning via "rm -rf".  It's also dead-simple, with this method, to tell your version control system to ignore your build outputs tree and easily see what you've changed without having to have that view cluttered up with derived files.
