md5sum

[Cathey, Jim]

"cat $FILELIST > /dev/null &" will prepopulate your cache for you, and
should 
do it on a separate processor from the md5sum process.  (I take it this
is 
jffs2 log reassembly and decompression?)

Yes.  It took 11.5 seconds to cat every file in the list to /dev/null,
so in fact it's a net loss over the -j2 option to md5sum!  The second
catting took 0.2 seconds, obviously the big loss is in jffs2.
