I don't know JFFS2 too well either, but im sure with a single filesystem, it will serialise access to the flash. When there are multiple filesystems mounted from the same flash i've no idea if simultanious access to different filesystems are serialised. It could be than in the Linux world the MTD layer sorts this out?
