-// Summary:
-//   Closes a socket, with option to attempt it multiple times.
-//   Why do this? Well, if the system-call gets interrupted, close
-//   can fail with EINTR. In that case you should just retry.. Unfortunately,
-//   we can't be sure that errno is properly set since we're using a
-//   multithreaded approach in the filter proxy, so we should just retry.
-// Args:
-//   fd - the socket to close
-//   tries - the number of tries to close the socket.
-// Returns:
-//   true - if socket was closed
-//   false - if socket was NOT closed.
-// Side-effects:
-//   sets *fd to -1 if socket was closed.
-//
