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.

We added a new internal _Py_AddPendingCall() that operates relative to the

ask another interpreter to do work that cannot be done in the current

interpreter, like decref an object the other interpreter owns. The existing

Py_AddPendingCall() only operates relative to the main interpreter.
