Why on Earth are virtual addresses hardcoded into DLLs?  Do UNIX systems
do this for shared libraries?  I've never heard of such a thing under

Shouldn't the NT kernel's page tables allow DLL text and data sections
to be loaded at any virtual address without requiring a copy of the DLL
to be made (i.e., rebasing)?

Just curious.
