vda@port.imtp.ilyichevsk.odessa.ua: SAK messages:
  I use SAK from time to time when I have problems with hung processes.

  Sometimes it is difficult to figure out what was being killed and why.

  For example, Midnight Commander contains a bug: it holds fd#3 open to
  the tty. It prevented me from daemonizing processes (like X) - they
  died upon SAK.

  This little patch makes SAK tell whom and why it kills. Tested.
