 > Any chance of getting a unit test for the new code here?

 I have no idea how to begin to create a unit test that replicates the
 conditions of this bug when calling `connection_handle_read()`, there
 aren't any pre existing unit tests of that function to learn from example.

 For better merging to 0.3.5:

 https://gitgud.io/onionk/tor/compare/master...inbufoverflow1-035

 For 0.4.3:
