Some OSes, *cough*-dows, insist on stack being "wired" to
physical memory in strictly sequential manner, i.e. if stack
allocation spans two pages, then reference to farmost one can

Both volatile and "memory" are used because of some concern that the compiler
may still cache values across the asm block without it, and because this was
