Most of the processes you're seeing are run by the session upstart.  Try
'ps fax' to see the process tree.  You also get to see what state these
processes are in that way.

Still, this has nothing to do with Unity, which neither handles system
power states nor session process control.  You might want ot check logs
in /var/log/upstart or ~/.cache/upstart for more clues.

Title:
  Duplicate processes started after Resume of amd64 bit

  I typically run Thunderbird, Firefox, a terminal or two, Gthumb, Gimp,
  Qcad, Gedit, Libreoffice, Inkscape, Document Viewer and occasionally
  Virtualbox.

  I just noticed this a couple of weeks ago, so I am guessing a recent
  update started it.

  It seems to me that there are quite a few duplicate copies of some
  processes populating memory after suspending/resuming a session for a
  few days.  Namely, dbus-daemon, gvfsd and gconfd-2.  The more I
  suspend/resume the session, the more of these processes appear.  After
  a while they start using up a significant amount of memory and system
  response seems to slow down.

  Logging out and back in did not alleviate the problem. Rebooting did.
  But, I will have to reboot again in a week to free up the memory used
  by these duplicate processes.

  The example session used to get the following results was probably
  well over a week in use.

  Before rebooting:
  $ ps -ef >prereboot.txt
  $ grep -i dbus-daemon <prereboot.txt|wc -l
  40
  $ grep -i gvfsd <prereboot.txt|wc -l
  78
  $ grep -i gconfd-2 <prereboot.txt|wc -l
  37

  After rebooting:
  $ ps -ef >postreboot.txt
  $ grep -i dbus-daemon <postreboot.txt|wc -l
  4
  $ grep -i gvfsd <postreboot.txt|wc -l
  5
  $ grep -i gconfd-2 <postreboot.txt|wc -l
