1. Close other client sockets in application forks …

   All client unix sockets are initiated at the spring application
   process before forking to serve each client. A reference to the
   client socket remains active by the thread in the wait method waiting
   for the client's fork to exit.
   
   This is problematic in cases with more than one parallel clients
   because the client socket for the first client is also present in
   the fork for the second client due to fd inheritance from the spring
   application parent process.
   
   With the first client's socket being present in the second client's
   fork, the first client cannot exit gracefully because a reference to
   its socket remains open in the fork for the second client leading to
   rails console hanging for the first client until the second client
   gets terminated.
   
   The problem can be reproduced by opening 2 rails consoles on spring
   & attempting to exit the first console while the second is still active.
