I'm unable to reproduce the infinite loop under XP. 
As far as I can tell this shouldn't produce one,
either: since I don't modify the value of hShell32,
FreeLibrary should eventually fail when the refcount
on the library reaches 0 and the library is actually
unloaded.

There are other problems in WinXP that I'm working on
(ILFindLastID doesn't appear to be exported by name,
for example).  If you're sure an infinite loop is the
symptom, though, I'll resubmit without this test. 
(Pity, it was probably the most interesting test.)
