Please drop the shm from this in a future spin. I could break the
internal state quite easily (like the very first torturous thing I
did) by dumping /dev/urandom to the shared memory file. I could very
easily craft something that will keep this shared memory in a bad state.
In fact, I haven't even tried to do things like overwrite existing
shared memory objects (should be possible, and will break other
projects, ecryptfs is the first that comes to mind). It would be better
to just drop it.
