More explicit list of limitations/restrictions on the underlying processes #71
Description
From the README it's not clear what the differences are for a process running normally and under quicken.
What is different:
- the environment, stdin/stdout/stderr, umask, cwd, sys.argv, pid will be different between the execution of the top-level code (e.g., imports, function definitions, global variable definitions) and the execution of the entrypoint
- signals to a quickened process are proxied to the actual process (source)
- the actual app being executed will be a child of the command server, not the users shell
- there may be a long time between execution of the top-level code and execution of the entrypoint (for edample, state retrieved at the top-level of an application may be stale by the time it is used)
What isn't different:
- global changes made from the application entrypoint onward will only exist in that instance of the application
TBD:
- atexit callbacks
