Thanks for your thoughts.

This is a very useful confirmation of my understanding of way the

Presumably I could also release the pressure at the slave cylinder.
This would be less messy and less likely to introduce air into the
system.  Do you agree?

In other words, I will follow this procedure.

  1) Park the car on a hill, in 2nd or 3rd gear.  Parking brake
     engaged.  This is Michigan, so hills are fairly hard to come by, 
     but I'll figure something out :-)

  2) Release pressure from clutch by opening and closing the bleeder
     valve at the slave cylinder.

  3) Without touching the clutch, start the car, in gear.  Drive the
     car in this gear, without using the clutch, to see if the
     slipping is still there.

To you agree that this procedure catches the spirit of your
suggestions?

Sounds very promising.  Stay tuned.
