For standalone unix sockets, listen() will fail if we haven't called bind()
with an actual address. If we remove the name on dump, we won't call
bind(), and thus sockets in this state will fail to restore.
v2: temporarily rename a unix socket out of the way if necessary in order
to bind() correctly and then delete it (e.g. when there are two unix
sockets bound "on top" of each other)
v3: remove extra unlink(), do the real unlink() in bind_unix_sk() so we
only need to do it once

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
