No. There were actually a few problems: - A mistake I made in the compat_linux futex syscall stub that redirects to the native. - A difference in how process lookup works between NetBSD and Linux that was accidentally removed when the LWP ID overhaul changes were made. - Some latent bugs in argument handling in some of the scheduling-related Linux syscalls. I'll check in fixes for these tonight. -- thorpej
