title: Webrick will not stop or restart
body: <p>I was running Linux Mint 13 prior to now, and just switched to Fedora 17. Since I have made the switch, I can no longer stop Webrick. I use Jetbrains Rubymine, and starting the server works fine, but as soon as I hit stop, or restart, it somehow detatches from the processes and I cannot use that port again until I reboot my computer. My first thoughts were that it was a problem with Rubymine, but when I start the server in a console, it does the exact same thing. I hit <kbd>ctrl</kbd>-<kbd>c</kbd> to stop it (and it appears to do so), but as soon as I go to start the server again on that port, it fails because of duplicate address in use.</p>
