Lots of them, too. With 2.0.4 and 2.0.5, 24Mb RAM, 64Mb swap. Because I
upgraded and installed (and activated) my ISDN card at the same time,
I don't know what's causing it.

Here is free after a clean boot (xdm and X11 waiting on another VC):

root@bofh:~# free
total used free shared buffers cached
Mem: 23076 18644 4432 13420 1540 8016
-/+ buffers: 9088 13988
Swap: 65840 0 65840

I start working, get lots of "Couldn't get a free page",
"ippp0: Memory squeeze, dropping packet", etcetera. I leave my X11 session,
leaving the system in essentially the same state as after clean boot, and
this is the result (after multiple ISDN connections, loads of news
coming in, some kernel-compiles, Netscape sessions, etcetera):

root@bofh:~# free
total used free shared buffers cached
Mem: 23076 18888 4188 4484 680 4708
-/+ buffers: 13500 9576
Swap: 65840 3980 61860

A quick check of ps -aux showed that none of the user-level programs were
doing serious memleaking. I'm bad at interpreting free's output, but I think
something is rotten...
