I believe this "pre-linking" actually started with IRIX 4.0
in 1991 where the X server had a dynamic linker which loaded any
machine dependencies ( much like XFree does now ).  It pre-processed
the modules to "semi"-random ( but "high" ) addresses;  With luck, which
in actuality was always for the customer ( though not in the testing labs ),
the library would be mmap'd as two contiguous segments and no linking was
done at all -- If this wouldn't work, the entire object would be linked
( yes, with all the weird MIPS fixup-types handled ).

P.S.  This was a BSD-scented SVR3+ using COFF still.
