Most of my patches (for SIGINT) are exactly doing that: check the exception 
type instead of "if (result == NULL) PyErr_Clear();" (try/except: pass). About 
initsite(): I consider any error as fatal. If initsite() failed, something 
goes wrong.

I think that my patches are enough to catch SIGINT during the Python 
initialization. I used different tricks to test Python: add kill(getpid(), 
SIGINT), use "signal SIGINT" in gdb, add 
PyErr_SetNone(PyExc_KeyboardInterrupt), ... valgrind is a very good tool to 
slow down any process :-D
