My subr_prf.c is the latest (1.19) (and yes, I only got 1 message per second,
but that still seems a lot). As far as firefox is concerned, I'm running, but I also noticed something else. I left the machine on overnight
(but killed firefox before I did that) and the exact same message appears for
knode, kmail and one of the kdeinit processes (but these don't seem to get
stuck, but seem to continue working without problems).
