Why are libraries being preserved?

When exactly are those consumers detected?

When exactly does this happen? At the end of any emerge action?

When and why? Do I run this once? Do I need to run this often?
Besides these questions, the transition from revdep-rebuild to
@preserved-rebuild may be worth a note as well; if I remember correctly
you have to do one last revdep-rebuild when you enable this feature, or
in other words preserve-libs won't detect present inconsistencies. I
feel like this should probably be documented as well, as part of
mentioning that this is intended to replace revdep-rebuild...
