This seems a little excessive to me. On my 486-33 (DX) I can increment a long long or a short ten million times with a time difference of only about 1.25 seconds, total time is 5 - 6 seconds. (This is with the 8k cache). Note this is also with no optimization.
So if you lose 1.25 seconds in the week or so that the counter flips over on a 386...
