I remember someone explaining this before.  It went something like this: 
  The atime update happens whenever something is accessed.  Something 
(/bin/atime?  not on my system) needs to be accessed in order to make 
that update.  So, every five seconds, there _will_ be a new atime that 
must be written, and since ReiserFS3 doesn't do lazy writes, it _will_ 
be flushed out to disk.  (Reiser4 would just keep it in RAM until memory 
pressure or a sync/fsync forced it out to disk.)

So, the simplest way is to do "-a noatime", unless you really need the 
atime updates.  It'll boost your performance, too...

But this is all from memory, from a long time ago.  I have no idea if 
any of the above is still true.

Nor Gentoo, but I use it there anyway.
