we can share this between the two branches provided you initialise worker_cache_factor correctly.

Right, sorry, I managed to mess up testing this. Two sticking points:

  1. synapse.app.homeserver doesn't look at worker_pidfile etc
  2. There's a few places where we assume if worker_app is None then we're a worker.

For 1 I've made synctl complain if it sees worker_ config and for 2 I've canonicalised worker_app to be None if its the main process

I can't help thinking it would be better if synapse.app.homeserver did look at the worker_* options?

Yes, or even to not have the duplication between worker_pidfile and pidfile params, but I think that ends up with quite a bit of synapse fiddling (which I'm not enthusiastic about dong right now)
