Yeah, I thought this too. And in fact, I also did a revdep-rebuild
for the 4.1 upgrade and did not experience any problems between then
and the time I eventually did an emerge -e world. But check the
archives of this list from around the time when gcc-4.1 hit ~arch, and
you will see that that did *not* work for everybody. We learned the
hard way that the safe route is emerge -e world.
And it isn't just my say-so...the gentoo devs insist ([1] & [2]) that
the emerge -e world is the only safe option. They don't say these
things because they want users to waste a bunch of time...
