Lifting defects for nonstable K_0-theory of exchange rings and C*-algebras

Additional note: the question, following Proposition 12.7, whether \vec{K} has a lifting satisfying hs=s and s^2=1, has a positive answer, that I had overlooked at that time.This answer is obtained via an easy modification of the construction in the proof of Proposition 12.7.
