[New-bugs-announce] [issue25787] Add an explanation what happens with subprocess parent and child processes when signals are sent

[Karl Richter]

New submission from Karl Richter:

The [documentation of subprocess](https://docs.python.org/3.6/library/subprocess.html) doesn't contain a substantial statement how signals are handled which are send to the python interpreter. After reading the referenced docs it should be clear

  * whether a signal is passed to both the parent and the child (If yes in which order? What happens if the child process spawns a process which isn't controlled by python?)
  * whether signal handlers are inherited (judging from the `restore_signals` parameter some are overwritten -> what's the purpose of this?). Are changes of a signal handler in the parent reflected in the child?
