Code review comment for lp:~gz/bzr/test_ssh_client_medium_eintr__read_bytes

This does make the bug more clear, thanks for posting it. Clearly we
should fix _read_bytes.

I'm not super keen to actually merge this because history shows that
any test that depends on timing interactions between threads will
intermittently fail in the future. Do you really want us to?
