Bug description:
  It looks like the Swift proxy will leak memory if the connection is
  closed and the full response is not read. This opens for a potential
  DoS attacks.

  Reproduce:

  $ swift -A http://localhost:8888/auth/v1.0 -U .. -K .. upload --use-slo --segment-size 1048576 <container> <big-file>
  $ curl -H'X-Auth-Token: AUTH_...' "http://localhost:8888/v1/AUTH_../<container>/<big-file>" -m 0.001 > /dev/null

  Repeat the curl command a couple of times and you will have more
  information in netstat and sockstat. The important part is the -m
  which sets the max time curl spends at downloading. After that point,
  it'll close the connection.

  $ sudo netstat -ant -p | grep :6000
  $ cat /proc/net/sockstat

  tcp        0      0 127.0.0.1:6000          0.0.0.0:*               LISTEN      1358/python
  tcp        0  43221 127.0.0.1:6000          127.0.0.1:48350         FIN_WAIT1   -
  tcp        0  43221 127.0.0.1:6000          127.0.0.1:48882         FIN_WAIT1   -
  tcp   939820      0 127.0.0.1:48350         127.0.0.1:6000          ESTABLISHED 17897/python
  tcp   939820      0 127.0.0.1:48882         127.0.0.1:6000          ESTABLISHED 17890/python
  tcp   983041      0 127.0.0.1:48191         127.0.0.1:6000          CLOSE_WAIT  17897/python
  tcp   983041      0 127.0.0.1:48948         127.0.0.1:6000          CLOSE_WAIT  17892/python

  Restarting the proxy frees up the lingering memory.

  This problem did not exist in 2.2.0.
