Please see mod_ruby and the way that it handles this with garbage
collection.  There is no way to do this from the script side as far as
I can tell.  You can't unload shared objects yet.  knu and I had an
interesting discussion about that on IRC and I was going to play
around with trying to integrate how apr handles this.  Under
APR/Apache the memory never gets freed for shared objects, instead the
pointer to the shared object resource gets moved to a new location
where the memory exists.  I believe that it is possible to unload a
DSO under FreeBSD (maybe linux), however there is no cross platform
way of accomplishing this.
