Title:
  Slow shutdown/restart on saucy with sendsigs waiting 10 seconds

Status in “sysvinit” package in Ubuntu:
  Confirmed
Status in “sysvinit” source package in Saucy:
  Confirmed

Bug description:
  I've the S20sendsigs waiting 10 seconds on each shutdown, making the
  shutdown slow.

  I hacked around to debug it (probably completely wrongly), and ended
  up with the attached pids.txt. What is shows are the processes still
  after 9 seconds spent in the killall5 loop, with the pids from
  OMITPIDS removed from my ps ax output. It leaves only init, kernel
  processes, S20sendsigs itself and initctl which in my opinion should
  be enough not to wait for yet another second? The same output is there
  after two seconds already.

  I've workarounded it now by changing the "for seq in 1 2 3 4 5 6 7 8 9 10; do" to "for seq in 1 ; do" which gives me a snappy shutdown back.
