We had two independent patches (also trying to get NetBSD, Darwin and Linux compat) and enhancement, which are currently under review. FreeBSD 9 has spares for this so it can be merged to stable/9 easily. The change will add KEEPINTVL, KEEPCNT, KEEPINIT and KEEPIDLE (badly named but already pseudo industry standard).
