To name a few, deleting a socket implies that:

a) any file can be accidentally deleted due to a typo in the 
   listen directive;

b) attempts to do duplicate listen are not detected and silently 
   break service, e.g., if you start duplicate instance of nginx.

Instead we delete the socket after closing it.
