Ok, maybe there were some misunderstandings, I was looking for some real life 
questions...
Let's assume this one:
  "What were the first three actors accessing '/home/markus/seif.txt'"
With the current definition of LeastRecentActors the query would look like
  >>> template = Event.new_for_values(subject_uri="/home/markus/seif.txt")
  >>> events = FindEvents(TimeRange.Always(), [template,], Any, 3, 
LeastRecentActor)
  >>> actors = [e.actor for e in events]

This would not work anymore if we do the change you propose. So what I want you 
to tell me is:
  * How will the query look like in your definition?
  * Can you give me a similar question which gives a usecase for your 
definition?

Bug description:
In an attempt to work on bug #641968 I discovered that we some of us defer on 
the understanding of LeastRecentActor

The documentation stated that LeastRecentActor = enum_factory(("The first event 
of each different actor"))

Let's assume we have sequential events. (The actors are defined by numbers)

2, 1, 3, 2, 1, 4

So we have 4 different actors (1,2,3,4) and we want to sort them by least 
recent.
the least recent is not 2 or 1 since they are used again at the end. the least 
recent is 3

This means LeastRecentActors should return the latest actors sorted ASC:

3, 2, 1, 4

and not

2, 1, 3, 4

When we look at LeastRecentSubjects = enum_factory(("One event for each subject 
only, "
  "ordered with oldest events first"))
My understanding according to Siegfried is:

<seif_> RainCT,
<seif_> LeastRecentSubjects = enum_factory(("One event for each subject only, "
<seif_>   "ordered with oldest events first")
<seif_> so i f i have
<seif_> the subject
<seif_> 1, 2, 1, 3, 4
<seif_> what do i get returned
<seif_> 1, 2, 3, 4
<seif_> or
<seif_> 2, 1, 3, 4
<seif_> ?
<RainCT> seif_: the later
<RainCT> for each subject you only look at the most recent one
<seif_> ok then we should do the same for the actors :)
<RainCT> Yes. Isn't it like this already?
<seif_> no

In that case if we follow this convention I can update the doc strings and 
already have the bug fix for both this bug and #641968
