I realised it was 50-odd in the rebuild list, but in my experience
multiple runs gradually reduces that number. Maybe portage could be more
intelligent about the order in which it re-emerges these packages, but
running it enough times always works for me.

Removing the registry is potentially risky because you could still have
packages linked to a library that is not managed by portage, and that
will never update. If someone finds a security hole in that library, you
could be in trouble.

"Fixing" the problem by deleting the registry is akin to fixing low oil
pressure in your car by disconnecting the warning light.
