Have a look at this paper from the Mungi people: Luke Deller, Gernot
Heiser: ``Linking Programs in a Single Address Space''
<URL:http://www.cse.unsw.edu.au/~disy/papers/Deller_Heiser_99/paper.ps.gz>.
My impression from this paper is that the problem of shared libraries
in SASOSs is well-understood.
