I'm slightly surprised at the 5% figure.  Martin Jansa posted some
statistics in another thread earlier today which showed an improvement
from prelink of just under 0.5% (0.24 seconds saved out of 49.51 seconds
total) and that's more like what I would have expected.  What sort of
binaries were you running on the system you measured?

I also don't entirely understand the fragmentation argument.  We're not
talking about a no-mmu configuration here, are we?
