Subject: UNIX sockets kernel panic

The following code causes a kernel panic on Linux 2.6.26:
http://darkircop.org/unix.c

I haven't investigated the bug so I'm not sure what is causing it, and
don't know if it's exploitable.  The code passes unix sockets from one
process to another using unix sockets.  The bug probably has to do with
closing file descriptors.
