Woot!

Another wrinkle: I have since discovered that badly behaved
client systems can produce overlay directories that are hard to
clean up (e.g. it takes too long to delete the million fifos one left
behind in /tmp), so I may change the script to create a filesytem
using loopback mount on a file.   This is getting kind of complex,
especially the cleanup!
