Exactly controlling the state of the RTL. Either to be exactly the same in
the dynlib and the mainprogram, at least for the cases that matter.

That is correct, those are the most important ones. There is no end user
safe way to my knowledge, just limited experiments of people that knew what
they were doing. (or were lucky)

Packages is the only long term way. Unless your interface between the DLL
and the program can be really limited and rigid. Then you might have luck
the manual way.
