As far as I read the code, if OutgoingRunner catch SIGINT during waiting
for response from the MTA, the signal handler for SIGINT in qrunner set
flag to exit from loop, then socket module raise socket.error for EINTR,
but SMTP module retry to read from socket and waiting for response until
receiving response or connection closing (from MTA side or by error).
Thus it cannot reach to the code to exit if the connection is kept alive
and MTA send no data.
