- this causes POSIX locking to use the thread group leader
(p->p_leader) as the locking thread for all advisory locks.
In non-kernel-threaded code p->p_leader == p, so this will have
no effect.
This results in (more) correct POSIX threaded flock-ing semantics.
It also prevents the leader from exiting before any of the children.
(so that p->p_leader will never be stale) in exit1().
We have been running this patch for over a month now in our lab
under load and at customer sites.

after demand of two people and no objections:
- included all registered protocols, so it's now a useful reference as well
- renamed title to reflect new content

- corrected URL (file isn't hosted by iana.org anymore)
This means that the driver will add/delete routes when it knows it is
up/down, rather than have the generic code belive it is up if configured.
This is probably most useful for serial lines, although many PHY chips
could probably tell us if we're connected to the cable/hub as well.

Do discard standard output from the sysctl for approxy_all, and echo
what this sysctl is doing in the usual way. This fix is probably
backwards. We should probably just use the standard sysctl output
in all cases (it needs to have a newline filtered out).
Echo what the sysctls for nfs_reserved_port_only and nfs_access_cache
are doing.

Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL. This happens a lot with

There is no detectable increase in network trafic because of this:
