It looks like the atari implementation does not do this correctly for kernel
threads since they will never reach the call to 'rei' in proc_trampoline
that does the spl0(). So I think we should add:
to the start of proc_trampoline. The amiga should do this too and I suspect
the rest of the m68k ports also.
It would be nice if someone else can check this conclusion.
