Mike Silbersack 0709c23335 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.
