Since the introduction to Watchman, with the failover to StatReloader, the 
file changes aren't picked up.

We're running our Django development environment in Docker/Docker-compose, 
and 2.1.7 everything is still fine. But updating to 2.2.0, the file changes 
aren't picked up (or rarely).

We have installed Watchman in our docker, but then there was a timeout.

Any suggestions on how to fix watchman or make StatReloader work as it was 
in Django 2.1.7?
