Yes, except that I can't think of one that's feasible that doesn't have to do with I/O - which isn't a problem if you are using the proper accessor functions. Such an example has to involve more than one CPU, because you don't tend to get memory/memory ordering problems on UP. The obvious one might be circular buffers, except there's no problem there provided you have a memory barrier between accessing the buffer and updating your pointer into it.
