Blockdevices only use ZONE_NORMAL for their pagecache. That cat will
selectively put pressure on the normal zone (and DMA zone, of course).

You must have a lot of files.
Actually, I expect a `find /' will only stat directories,
whereas an `ls -lR /' will stat plain files as well. Same
thing for dcache, but the ls will push the icache harder.
I don't know if updatedb stats regular files. Presumably not.
