More interesting still: I think things might blow up if the .la files
have been removed on a platform that does automatic deplib loading for
runtime linking, say lt_dlopening libpng.dll (which pulls in zlib
through LoadLibrary without libltdl knowing about it), and then the
application tries to lt_dlopen libz.dll.  It then depends on whether
the underlying LoadLibrary implementation is smart enough to realise
that it already has a copy of libz in memory and returns a handle to
it without trying to reload another copy first... this would be an
interesting test to have in the next release to see what feedback it

Obviously this is already working fine. Windows LoadLibrary() is smart enough to know what it has already loaded. The unloading sequence is much more interesting since something could be unloaded which is still being used.
