This is foremost a kernel issue.  If the kernel people decide on a
common scheme to handle atomicity for architecutres without support I'm
sure we can come up with a set of user-level functions which is
uniform.  Your stack pointer hack seems not too bad but the cost of the
extra check in every syscall etc seems high.
