Note that, in Windows, SIGINT and SIGBREAK are implemented in the C
runtime and linked to the corresponding console control events in a
console application, such as python.exe. Console control events are
delivered on a new thread (i.e. no Python thread state) that starts at
CtrlRoutine in kernelbase.dll. The session server (csrss.exe) creates
this thread remotely upon request from the console host process
(conhost.exe).
