Bug description:
  [regression] Mir servers crash on client input - std::exception::what:
  Client input channel write blocked : 11, "Resource temporarily
  unavailable"

  ERROR: /home/dan/bzr/mir/trunk/src/server/input/android/input_sender.cpp(197): Throw in function void mir::input::android::InputSender::ActiveTransfer::send(uint32_t, const MirEvent&)
  Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
  std::exception::what: Client input channel write blocked :
  11, "Resource temporarily unavailable"

  Test case:
    1. Start a Mir server
    2. Start a non-input Mir client like mir_demo_client_scroll or mir_demo_client_flicker

  Expected: Client ignores mouse input and keeps working.
  Observed: Server crashes on mouse motion over the client (scroll) or on mouse click (flicker)

  The bug appears to be in lp:mir only. Not in lp:mir/0.18
