Two very different things:

I am not aware of any changes that could justify that it no longer 
should work on Windows. It is our code talking directly to the queue 
through Celery - I would not expect TurboGears to play any role in that.

The most likely culprit is the upgrade from Celery 2 to 3.

So ... if it is broken on the default branch, I guess that "just" is a 
bug. Perhaps some oversight in the upgrade, or an issue in Celery 3 
(there are probably reasons they gave up supporting it).


Then, long term:

Celery might be needed for big setups, but it might not be a good idea 
to run those on Windows anyway. And those who do are probably companies 
who can afford to get in touch with Celery and get support or sponsor or 
contribute development. We will have to move on from Celery 3 at some 
point. It would be sad to lose Windows support in an upgrade to Celery 
4, but that might be the best option.

But also: we only use a small part of Celery. It is probably feasible to 
keep that part working.
