I'll test that myself (but in a bit - I need to go do voter registration and socsec update first, though - I became a US citizen last week).
Because yes, that's the reason I'm personally interested in your scheduler latency work: I think our X behavior under load is pitiful (I do "make -j16" on my dual-core with HT Core i5, and web browsong shouldn't start to lag as much as it does just because I overcommit the CPU a bit). So if this makes a noticeable difference, I think it's very important.
