I can't give any Guarantees, but I've never seen a longword fetch or
store be interrupted by other types of accesses (except that the PC pushed
during interrupts is pushed in two pieces with other stack accesses
inbetween).  Note however that if your system arbitrates for the
68000 bus (using BR/BG/BGACK), anybody can break in to a movl with a DMA
cycle.
