If Django's runserver buffers its output, there's nothing Honcho can do about that. You can verify that this is not a Honcho issue by setting PYTHONUNBUFFERED=1 in the Procfile just for the Django process.

Ditto here.
[marca@marca-mac2 honcho]$ python -V
Python 3.4.2
[marca@marca-mac2 honcho]$ cat Procfile
web: cat
Without PYTHONUNBUFFERED, I get no output until I hit Ctrl-C:
[marca@marca-mac2 honcho]$ honcho start
^C13:43:22 system | web.1 started (pid=85574)
13:43:26 system | SIGINT received
13:43:26 system | sending SIGTERM to web.1 (pid 85574)
13:43:26 system | web.1 stopped (rc=-15)
With PYTHONUNBUFFERED=1, I do see it output web.1 started right away:
[marca@marca-mac2 honcho]$ PYTHONUNBUFFERED=1 honcho start
13:43:30 system | web.1 started (pid=85578)
^C13:43:32 system | SIGINT received
13:43:32 system | sending SIGTERM to web.1 (pid 85578)
13:43:32 system | web.1 stopped (rc=-15)

This seems to only happen on Python 3; it does not happen for me with Python 2.7.9.

Same behavior on Python 3.2 and 3.3.

Just a minor remark: The issue was introduced in the 0.6.x series. 0.5.0 works fine, every newer version has this issue.
Tested with python 3.4.x.

I also have this issue when using 0.7.1, even with Python 2.7. In the example below you can see that the Django startup message is swallowed if PYTHONUNBUFFERED is not set:
