Could you evaluate (nnml-marks-changed-p "nnml+foo:bar") to see if it
always return t?  Maybe you could edebug through `nnml-save-marks' to
see what happens?

On theory would be that the `stat' call Gnus does comes too quick
after writing the file, maybe the writing takes the path through the
local AFS cache stuff and the stat goes directly to the server so the
stat call will see the old modtime that is updated seconds later?
Maybe you could compare the modtime returned in `nnml-save-marks' with
the value you get if you do this a few seconds later.

But I don't know anything about AFS, maybe someone else knows more.
