I have to say that the vm-patch against t8p5 works fine here on t8p6

I've tested to copy a few big files between partitions and it didn't swap
at all (it used to swap like crazy leaving me to watch my frozen X during
the copy)

so far so good....

then a friend started a ftp-session against my machine and started to copy
a few files (3-6MB each via 100Mbit network) and my machine began swapping
like there was no tomorrow.

after about 15-30 seconds of heavy swapping the swapping stopped, now I
had about 35MB swapped out (I have 256MB ram, and the box is very light
loaded, no big memoryhogs or anything (not even netscape :))

I took a look at /proc/meminfo and I had more than 200MB in active pages
and almost nothing in inactive pages. So this is a case where drop-behind
doesn't work yet.

I should say that my ftpserver is proftpd-1.2.0pre10, a quite common
ftpserver
