I'd like to do this, so's to allow dynamically changing SOMAXCONN
without requiring a kernel build/reboot.  Anyone object?
Any other static params to do while I'm in there?

this affects listening sockets in all protocol families, so I think it
should go in a socket-level part of the mib. Does creating net.socket
and putting it as net.socket.maxconn sound OK?
(or lisen_queue_max? Any prior art, in Tru64, Solaris, ?)
