  SVN rev 189074 on 2009-02-26 15:51:54Z by ed
  
  Remove even more unneeded variable assignments.
  
  kern_time.c:
  - Unused variable `p'.
  
  kern_thr.c:
  - Variable `error' is always caught immediately, so no reason to
    initialize it. There is no way that error != 0 at the end of
    create_thread().
  
  kern_sig.c:
  - Unused variable `code'.
  
  kern_synch.c:
  - `rval' is always assigned in all different cases.
  
  kern_rwlock.c:
  - `v' is always overwritten with RW_UNLOCKED further on.
  
  kern_malloc.c:
  - `size' is always initialized with the proper value before being used.
  
  kern_exit.c:
  - `error' is always caught and returned immediately. abort2() never
    returns a non-zero value.
  
  kern_exec.c:
  - `len' is always assigned inside the if-statement right below it.
  
  tty_info.c:
  - `td' is always overwritten by FOREACH_THREAD_IN_PROC().
