Looks nice, and it seems they are even able to run BSD socket
emulation over that. Wow.

However, it is still mid-ugly:

       Opening  the  clone  file reserves a connection.  The file
       descriptor returned from the open(2)  will  point  to  the
       control  file,  ctl,  of  the  newly allocated connection.
       Reading ctl returns a text string representing the  number
       of the connection.  Connections may be used either to lis­
       ten for incoming calls  or  to  initiate  calls  to  other
       machines.

So, you open "clone". That creates directory for you. You can get its
number by reading from "clone" file.

That's pretty strange, agreed?
