Patch from Chris Demetriou to unmap an object on last dlclose(), which
...
had not be implemented. It would cause an "adress space leak" and, if
the same object would opened multiple time, unwanted relocations.
Re: Comment from Chris:
"The a.out ld.so has some problems with dlclose. It doesn't properly
unmap objects which are dlclosed. That's a known problem (though a
serious one for programs which dlopen then dlclose lots of objects,
because it causes address space exhaustion), but it has a
previously-unknown side-effect.
If a single object is dlopened, then dlclosed, then dlopened _again_,
the relocations will be processed again. That causes obvious
problems."
