Reduce the number of tcp time_wait structs to maxsockets / 5; this ensures
that at most 20% of sockets can be in time_wait at one time, ensuring
that time_wait sockets do not starve real connections from inpcb
structures.
No implementation change is needed, jlemon already implemented a nice
LRU-ish algorithm for tcp_tw structure recycling.
This should reduce the need for sysadmins to lower the default msl on
busy servers.
