Thank you for your answer, Sean.
I've tried 2.4.19-pre6 (with preempt-patch), 2.4.19pre7ac2 (with rmap),
2.4.19-pre7aa2. The rmap kernel behaved a bit better by avoid swapping-out
to swap-in a second later (compared to aa), but still suffered (IMHO) from an
oversized cache. The stock kernel was the worst one, of course.
The final cache size doesn't seem to depend much on the kernel, that's because
I asked for VM tune parameters. I also noticed that aa kernel dropped cache
size down to 24MB, but only after one hour without any activity (had
lunch...). BTW, please cc me, I'm not on the list,
