Seif, can you please give tow different usecases, one for the old
definition of LeastRecentActors and one for your new one. Please also
try to explain how changing the definition will influence real world
usecases.

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
