well, thats good to know. i guess i could have written a test just
like you did, but was pressed for time :) its why i put in the "my
impression is", just to try to cover my ass ...

a posting on linux-kernel a couple of weeks ago revealed just how easy
it is. the answer is "very easy". someone wanted to load a C++ module
into the kernel, which results in the same set of problems and
absolutely no chance of loading libstdc++ :)

semantics of dlopen were the same.
