Thanks to the great work of the gentoo KDE packaging team, I have been able to update to KDE 4.2.1 yesterday. And since then, a couple of processes suck up all my CPUs.
The first one is a well-known issue : lancelot does that when used with Qt 4.5. Ok, this one was quick to remove.
The second one is plasma. Somehow I was not really surprised : it often happens. I usually first blame gentoo for that, and I’ve tried to re-install a few things in order to fix it (like emerge @preserved-ebuilds, and so on…). But actually, that was not the problem. On #gentoo-kde, some other people seem to have either this very same problem, or worse (crashes). Removing your ~/.kde4.2 directory is said to help. That’s too much a loss for me so I have spent a little time to narrow the solution a bit.
And finally the solution is to remove only share/config/plasma*. How come did I not first think about it ?
So if you have the same problem, hopefully now you know how to fix it.
