 6. a single-thread process can interfere with itself, since typically most of its data is writeable; the kernel cannot be responsible for preventing this category of interference   
 7. when dealing with a multi-threaded process, besides simple self interference, one must also consider cross-thread
    interference, where each thread can corrupt not only its own stack, but also the stack of every other process.
