Automatically clean up PF_UNIX sockets on process exit?

Is there any way to have UNIX domain sockets be cleaned up automatically when the process that created them exits?

If your application only needs to run on Linux, you can use an abstract unix socket (a socket where the path starts with a NULL byte). Abstract sockets are cleaned up automatically when the server process ends.

Either by fixing the application to let it delete (unlink) the socket file on exit, or if you know the location of the socket file:

fuser sockfile.sock || rm sockfile.sock

This checks if a process is using the file and executes an rm on it if it doesn't. You could put this in a wrapper script which actually executes the application and cleans up the socket file afterwards.
