  Modified files:
    sys/kern             sys_pipe.c 
  Log:
  We must pmap_qremove() pages that we previously pmap_qenter()'d before
  we can safely call kmem_free().  This corrects a serious corruption issue
  that occured when using PIPE algorithms other then the default.
  
  The default SFBUF algorithm was not effected by this bug.
