Turns out that the arch object, where the plugin is stored, changes 2/3 times
between process creation and loading the program file. So we could store the
pointer but we'd have to invalidate it on all these events. Ultimately we'd
spend the time saved doing invalidation.
Which is probably why things like Target::GetCallableLoadAddress just get a new
pointer each time.
You gave me some good ideas about simplifying this whole process though so I'm
still going to work on that.
