I certainly don't know a general solution for *nix. However, even old "single-task" DOS provides such a function and it's a great help that can be provided by programmer to scheduler in the underlying OS, so *nix systems should provide such function too, right? If they don't, you probably don't have anything better than sleep(0) anyway.
