Well, I tend to agree with your comments on the benchmark, but have observed that when starting a large number of forks from the same parent on 4.0-STABLE, the system sporadically hangs waiting in vm_wait for some processes to exit, despite not having hit max kernel processes permitted, or hitting a per-user bound (user rwatson created 2k processes, and starved login running as root). I assume this is a vm limitation. Also, setting maxusers rediculously high (512, say) seems to result in a panic on 4.0 once you exceed a decent number of processes. Haven't had a chance to track any of this down however.
