Depending on what your definition of DoS is, JFFS2 _without_ EBS or CS
could be considered that already.  If mounts take extremely long times
on any decent sized flash, that could be perceived as a DoS.

Think along the lines of "new ogg vorbis player with 4 GiB NAND flash
using JFFS2 as the filesystem".  You think people are going to want to
wait for anything over 2 seconds for their music to be available?

I know, I know... far fetched perhaps.  But not any more than your
mount/unmount loop :).
