[C++-sig] Why can't kill process by Ctrl-c in a boost.python module with an endless loop

[Jaedyn K. Draper]

Instead of Py_Initialize() (wherever it is you call it), try calling 
Py_InitializeEx(0). Py_Initialize() (or Py_InitializeEx(1)) binds signal 
handlers (including SIGINT) to send python exceptions instead of killing 
the process. This may be what's hitting you.
