        there is one more different behavior in two different startup
environment,there is a readline() call on a socket which will block when no data
send to server,with 2.8M memory startup python when I ctrl-C when readline is
waiting for input,instead of catching the keyboardInterrupt,python seg fault
with just one message "Python Fatal Error, Interpreter not initialized( version
mismatch)",but with the 5M memory startup python,it just catch the
keyboardInterrupt and exit normally
