this patch still makes my xmms skip on light io load (untar kernel
source, open lkml mailbox folder) while opening mozilla. Even after
mozilla is there xmms is still skipping. Processes take ages to spawn.
And no, I'm not in swap. A 'su -'is taking 10 seconds to procceed.
Same applies when rm -Rf'ing a kernel tree.
Here is some more data for the curious:

note the load of 11. I can even get it to 30 while doing 3 tar xf
bla.tar simultanously.

I'm going to fetch some fish in the next two weeks in poland, so I will
not be able to do any more testing from sunday on. Happy coding (while I
stick to O10 *g*)
