In directory sc8-pr-cvs1:/tmp/cvs-serv21370/scheme/rts

Modified Files:
        channel-io.scm 
Log Message:
Fix some problems with WAIT-FOR-CHANNELS:

- Initialize READY-{READ,WRITE}-CHANNELS to () instead of #f, because
  the #f's don't get overwritten when the whole thing is interrupted.
- Fix the cleanup code which was conditionalized the wrong way.
