IMHO this is how the shared libs concept should have been implemented
from the very beginning. An (efficient) IPC is so much better in the
long run than allowing everything to every module and hoping that it
knows what it does (far from the reality) and of course that it does
not abuse its powers (not extremely reliable).
There has been plenty of research around microkernels vs monolithic but
regrettably I am not aware of corresponding research for libraries as
IPC versus the monolithic ones.
