I like explicit load rather than put these in top level and generate a
global variable.
Think about two processes(let's say in websockify.py) both use this
module, top level code executed for a second time, the later process
may get a different config from the first.
But developer may fail to notice.
This will cause some trouble which is difficult to diagnose.
Nope, I don't
think it will cause any race. First of all, no running
config happens outside that module.
Second, that module will be imported only one time because they're
running in the same python process.
So do you still think it can cause any problem?
