I think it _is_ the case, but the problem might be that the refcount
is not zero, and therefore the shared library is not actually unloaded
and unmapped.  (I say "might be" because I still don't see the
scenario where this could happen, and I'm not sure if it does happen
the solution should be as suggested -- it could be that it's better to
not load the .eln the second time, i.e. make 'load' behave like
'require').
