Subjectpre-2.1.89-5 acting strangely when doing file-intensive operation
There's something strange in pre-5. I was running a perl-script, which
goes through a lot of files, in news-spool. Free showed this (only a
couple of seconds between each free):

So free memory approaches zero rapidly, and after that 20-40 MB is
freed. And used swap stays in 45 MB even if there's no need for
swapping. ps showed that over half of running processes were in
'SW'-state.
