There may still be a difference on 32 bit systems: I can NOT change the priority on a process at all - the normal user does not have access to do so.

To test this further I changed the view to "all processes" and found that the error occurs for any process with the priority set to "very high"

I then ran top as superuser and changed the niceness of pulse-audio to 0 (normal). The problem did not occur when selecting the pulse-audio process in 'system monitor'. I then changed the niceness back to -20 in top and found I could _still_not_get_the_error_ to occur.

I then rebooted and proved the error could still be created.
I then logged out and logged back in selecting Unity2d - the niceness is set to 0 (default) and the problem can not be recreated
I then logged out and back in with Unity3d and though the niceness is now -20 the problem can still not be created.

There seems to be a problem with the way the niceness is being set on boot.
