- This is a side effect of not running NIS and running netstat. Each
- invocation of netstat tries to connect to the NIS server
- to resolve port numbers. This involves asking the portmapper about
- some questions. Since netstat uses tcp (probably by specifying
- set*ent(stayopen)) you will be left with tha connection in TIME_WAIT
- state. Don't worry, they'll go away (if you don't look).
