@ -53,8 +53,12 @@ This module defines the following constants and functions:
.. function:: interrupt_main()
Raise a :exc:`KeyboardInterrupt` exception in the main thread. A subthread can
use this function to interrupt the main thread.
Simulate the effect of a :data:`signal.SIGINT` signal arriving in the main
thread. A thread can use this function to interrupt the main thread.
If :data:`signal.SIGINT` isn't handled by Python (it was set to
:data:`signal.SIG_DFL` or :data:`signal.SIG_IGN`), this function does
nothing.
.. function:: exit()
