Raises NoSuchProcess if pid does not exist.
Note that most of the methods of this class do not make sure
the PID of the process being queried has been reused.
That means you might end up retrieving an information referring
to another process in case the original one this instance
refers to is gone in the meantime.
The only exceptions for which process identity is pre-emptively
checked are:
- parent
- get_children()
- set_nice()
- suspend()
- resume()
- send_signal()
- terminate()
- kill()
To prevent this problem for all other methods you can:
- use is_running() before querying the process
- if you're continuously iterating over a set of Process
instances use process_iter() which pre-emptively checks
process identity for every yielded instance
