Bug description:
  Under heavy resizing (stress testing under Valgrind), my Mir client
  (Xmir) crashed with:

  [1444895332.392862] <ERROR> MirBufferStreamAPI: Caught exception at client library boundary (in mir_buffer_stream_swap_buffers): /build/mir-7io2Aj/mir-0.16.0+15.10.20150921.1/src/client/buffer_stream.cpp(169): Throw in function virtual MirWaitHandle* {anonymous}::ExchangeSemantics::submit(const std::function<void()>&, mir::geometry::Size, MirPixelFormat, int)
  Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
  std::exception::what: disconnected: no new buffers

  The strange thing is it's only the client that died. The server
  survived and I can connect new clients to it.

  Duplicate bug reports now show Unity8 is another such client suffering
  from this crash. It's occurring on phones in the wild.
