When the main interpreter exits due to an uncaught KeyboardInterrupt, the |
|

|
process now exits in the appropriate manner for its parent process to detect |
|
|
|
that a SIGINT or ^C terminated the process. This allows shells and batch |
|
|
|
scripts to understand that the user has asked them to stop. |
