What steps will reproduce the problem?
1. Run the web server code from effective go - 
http://gopaste.org/view/f6O0f
2. Try to kill the program (with ctl+c or sending kill signals like 2 or 
15)
3. It won't die unless you send a kill -9
4. If you send a signal 3, there's a weird error and a stack trace. 

What is the expected output? What do you see instead?
The web server should exit cleanly when it receives signals like 2 or 15. 

What is your $GOOS?  $GOARCH?
linux/386
