Sure...

1. Put a Windows machine (IP address X) and a FreeBSD machine (IP address Y)
   on the network somewhere.
2. Install the mpd-netgraph port on the FreeBSD machine and set it up
   as a PPTP server. Configure IPCP so that the client gets IP address Y
   (e.g., "set ipcp ranges X.X.X.X Y.Y.Y.Y").
3. Using Microsoft VPN adapter, connect to the FreeBSD machine via PPTP

Before this patch, you would get a kernel panic soon after the connection
was established. After, mpd should detect an error writing data (EDEADLK)
and close the connection, no panic.

Thanks,
-Archie
