I seem to recall that with the old symbol table code (what is in 3.0)
mex files were unloaded properly when they were cleared. I intended
to look at the problem before releasing 3.0, but maybe that was
something that slipped by. Anyway, if it is still true that they are
not properly unloaded, I don't have any plans to fix it for any 3.0.x
release.
I also though it was fixed now in cvs head, but that doesn't appear to
be the case. Clearing .oct files does seem to unload them. I don't
know recall now why mex files are not handled in the same way, at
least with the new symbol table code.
