You mean "pygame" here?

Right, it does. Most of the time, it does not appear in top, but from time to
time it shows 1.5-2.3% CPU (even 5.9% once). On average, it's certainly
below 1%.
Also, I wonder why Freevo should display anything (using pygame) at all while
a movie is running full-screen?

Hmm. I don't have goom installed ATM, so its speed should be quite
irrelevant, no? (There are no Gentoo packages for goom itself, but I could
install it of course if you want me to test it.)
The problem with the high CPU usage seems to become even worse. Lately we
watched a movie and had serious problems with A/V sync; remotely logging in
showed 15% CPU usage for the main freevo process (with a *paused* mplayer
showing a TV recording), and the rest 85% were eaten up by the recordserver
process (nothing in the logs). We had to wait around 3 minutes until it
would suddenly stop, and we could continue watching the movie. This happens
often, but last time I looked, the main freevo process was the one going
berzerk (100% CPU). Again, it took around 3 minutes until we could continue.
(Again, I removed kaa.display from the installation.)
I have taken word as a guide and kept a little behind the head, i.e. I have
now kaa r3819 and Freevo r11290.
Would it make sense to try activating your benchmarking code?
