This is a minor documentation nit.

Under the entry for `os.times()`, there is a description of the various fields it returns (e.g., `user`, `system`).

```os.times()
Returns the current global process times. The return value is an object with five attributes:

user - user time

system - system time
```

For the latter, the word `system` is hyperlinked to the `os.system()` entry. This probably goes without saying, but there's no logical relationship of system time (time spent in the kernel on behalf of the process) to the system command (which invokes a command via a shell), so the link should be removed.
