  Modified files:
    bin/sh               trap.c 
  Log:
  1) Fix longstanding bug:
  	trap 'echo xxx' 1 2 3 15
  	read x
  is not interrupted by ^C (due to restartable read syscall) and must be
  interrupted per POSIX
  Worse case:
  	read -t 5 x
  hangs forever after ^C pressed (supposed to timeout after 5 secs)
  Fixed by adding siginterrupt(signo, 1) after catch handler installed
  
  2) Do not reinstall sighandler immediately after it is called,
  BSD do it for us
