git is the source of truth for the copyright, copyrite (the tool)
was taking exponentially longer with each release, and it's
polluting the code with sometime as much as 50 lines of names.
Using `with threading.Lock():` directly has no effect.
Correct usage is:
```
lock = threading.Lock()
with lock:
...
```
This applies for:
* threading.Lock
* threading.RLock
* threading.Condition
* threading.Semaphore
* threading.BoundedSemaphore
