10 Alan's problem sounds like the one I've been having through several
11 kernel versions - the way I describe the symptom is that the system
12 "lurches" through its work. It's an i5 box with 4 GB simple RAM (4
13 cores, 8 threads).

15 I did mention this here a few weeks ago, but when I discovered that
16 killing BOINC, or reducing its allowed CPU load, seemed to cure it I
17 took no further action.

22 You may be onto something there. My genlop history of firefox goes back
23 to January, when 3.5.6 was installed together with sys-kernel/gentoo-
24 sources-2.6.32-r1. I don't remember when I first noticed the lurching
25 though.
