[users at bb.net] Buildbot-worker 0.9.3 fails to start on Windows

[Pierre Tardy]

Hi,

Buildbot at the moment only works with python 2.
We are working at the python3 port but it is not quite ready (I'm hoping we
can have worker support for 0.9.4 thanks to the great work from Craig)

As per the Windows support, we are supporting windows by running unit test
suite and integration suite on appveyor.
However, according to our statistics, we have no user accepting to send
info to the statistic server and running windows. :-(
So I cannot say "it works, we have people running it". We are however
interested in having windows users, and are willing to help as much as we
can.

You can see on the appveyor.yml how we install pywin32 and other buildbot
dependencies:
https://github.com/buildbot/buildbot/blob/master/appveyor.yml#L13

Let us know.
Pierre
