[racket-dev] results of dlopen (hence ffi) persistent across evaluations?

BTW, IIRC, there is a way to load a new copy of a library, but that
could be pretty bad.  Alternatively, there's probably a way to unload
a library, so perhaps this could be hacked -- somehow voiding all
references to code from it.  But I'm not sure if there's a sane way to
do that so other things don't break.  (Where breaking could also be
reloading a library over and over.)
