That's appreciated, thanks.  You're right, and also about Banyan.  And
not just breakage but also performance.  I'm sure I won't be left
behind entirely but I also hope it won't be too painful to switch
over.

Banyan makes use of that method in FileDirectory I committed to trunk
yesterday (directoryTreeDo:).  Important to Banyan would be for
FileSystem to be able to do that without creating much (if any)
garbage.  Is that doable?
