Comment 9 for bug 184519

I experience these 63 spawned processes as well, if for nothing else
(all CoW memory etc accounted for) it hogs the scheduler by making
it slower to sort the CFS RB-tree which is O(log n).

An Ubuntu user proposed the following patch to
autoconfigure the maximum number of consoles from sysfs:

http://launchpadlibrarian.net/15940846/0001-Autoconfigure-maximum-number-of-kernel-consoles.patch

which looks sane to me.

I made a graphical tool to display process migration etc in the system
and the plethora of console-kit-daemons really cloud the view.
