And IMHO Linux is *way* too willing to evicy clean pages of my

about choice, I wish there was more in the area of how memory is
used.
isn't this tuned enough by "/proc/sys/vm/swappiness" ?
Let me generate some data points for discussion. But the general answer
is no, I just want to try to have some numbers to discuss. I also want
to go back to some 2.4.xx-aa kernels, Andrea had some very nice things
in his bdflush code, and he was kind enough to explain to me how to tune
them so I avoided the worst case events.
