No. Deluge only uses the BlockStorage component for all it's flash
operations and utilizes multiple volumes.

There is a tradeoff between a little extra protection versus code
space. Presumably, a well-behaved application will stay within bounds.
Even if bounds checking is in place, there's no stopping an
application mounting an arbitrary volume and writing to it.
