The problem was, I think, mainfested by the changes to kern_exec.c which were applied to -current only, and not to -stable. I believe -stable still uses the vn_rdwr (without the necessary call to LEASE_CHECK, of course, the better to break NFS...). In normal operation, this problem should never manifest in -stable.
