v1.0.3

• Bug fixes
  • Remove catchall receive handlers that would capture GenServer.call
    messages when functions were called by multiple threads
  • Timeout all port calls just in case. This hasn't been observed to my
    knowledge, but seems like a sensable precaution. The timeout is absurdly
    long (500 ms) so it shouldn't trigger.
  • Pass errors detected by C code to Elixir rather than crashing
