Title:
  neutron-rootwrap-daemon explodes because of misbehaving "ip rule"

Status in neutron:
  Invalid
Status in oslo.rootwrap:
  Invalid

Bug description:
  Somehow, one of my deployments (ubuntu trusty64 based)

  root@devstack:~# uname -a
  Linux devstack 3.19.0-37-generic #42~14.04.1-Ubuntu SMP Mon Nov 23 15:13:51 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  results on never-ending output of "ip rule"

  # ip rule
  0:	from all lookup local
  0:	from all lookup local
  0:	from all lookup local
  0:	from all lookup local
  [...]
  runs for ever... (apparently because of a kernel bug)

  As a result of that, when neutron-l3-agent calls "ip rule" via
  rootwrap-deamon, the daemon eventually takes all the VM memory, and
  explodes.

  I believe we should include some sort of limit on the rootwrap-daemon
  command response collection to avoid crashing the system on conditions
  like this.
