In comp.sys.amiga, there's a discussion going on about adding MMU's to
the machine.  One problem is the Amiga's use of (shared) libraries.

How are they handled on machines with address translation?  Do they just
have to be written relocatable, or are assignments to virtual memory slots
done at compile time (yuk), or is there some other technique for fitting
them into the address spaces of various processes?

If it helps, the Amiga uses an `openlibrary' call which returns a pointer
to a table of pointers to library routines.  Routines are located at known
offsets.

Thanks for any info.
