If I remember correctly, (from what Mark has said), this error is caused 
not by Python or win32 alone, but by extraneous system factors affecting 
Python.

I've been able to workaround it with this in global.asa:

<SCRIPT LANGUAGE=VBScript RUNAT=Server>
function noOp()
end function
</SCRIPT>

<script language=Python runat=server>
def Application_OnStart():
	try:
		import signal
		signal.signal(signal.SIGINT, lambda a,b:None)
	except AttributeError:
		pass
	except ValueError:
		pass
</SCRIPT>


Desperate measures...
