No.  Should it?  Do you have an example to show what you're concerned
about?
I just remember (somewhere in this now-enormous thread) somebody mentioned that only the low 32 bits of handles are meaningful in order to allow sharing of handles between 64- and 32-bit processes. It seems that this would force dlls to load in the low 2/4GB of memory so that their handles are shareable. Perhaps (hopefully) the sharing thing only applies to HANDLE and not to HMODULE?
