Some processors support multiple stacks for multiple types of faults.
(i'm pretty sure m68k falls into that category.) That can make this
easier to handle, but it can't be done on all CPU families, and i'm
not even sure about whether or not it can be done on all members of
the m68k family.
Even the old 68000/68010 have seperate frames for the user stack and
an exception stack. (side note: 68000 based machines cannot be run
under linux, and 68010 systems with mmu are rare).
