I believe this will list the open memory-mapped files on your root 
partition:

lsof -d mem -a +f -- /

Out of the resulting list you can probably eliminate libraries that 
are being read but not written to. If /var is on your root filesystem, 
then there will probably be a bunch of mmap'ed stuff in the various 
directories inside /var.
