I didn't find any of those links terribly informative for
understanding the aspects of _how it works_ that I'm unclear on --
particularly, how it deals with the fact that the symbols it wants to
override for bionic-linked DSOs have the same names as existing
symbols from the system libc that need to be left visible.
