If the static object works for you, then maybe that's the simplest thing 
to do?  Otherwise, we could maybe add something that would call a 
function when Octave unloads the shared library.  Either in the 
dynamic_library class (lowest level) or in the dynamic_loader class 
(higher level, closer to .oct/.mex files).
