Attached is a patch to be squashed in to:

  Process the same signals as kill -l
  Output whether action failed or not
  Don't run sigaction(..set..) if get failed

I'm not that enthusiastic about the -p
since it treats PIPE specially here,
and it's not special from env's point of view.

cheers,
Pádraig
