   4 Subject: [PATCH] server: Fix fake "Address already in use" error
   5
   6 In the current workflow, socket file will be deleted if it already exists.
   7 However, if the socket file is a symbolic link and the file that it refers
   8 to doesn't exist, we will got "Address already in use" because bind()
   9 thinks the socket file exists and won't create it.
  10
  11 Now, use lstat() to determine whether the socket file exists.
