Comment:

 I added the checks to `s.SetDeadline` and `f.Close`, and added tests for a
 failing `s.SetDeadline`, in this series of commits:
  * https://gitweb.torproject.org/pluggable-
 transports/goptlib.git/diff/?id=3be4b5e2d3ba2add44e0d0307ad3f2487f8ad208&id2=737bb08d9520b27030c32884b0303c389b407671
 I decided that it's not worth breaking out a test for a failing `f.Close`.
