Smaug listener cannot be quit when waiting for connection on Windows

[qwewrty]

The SIGTERM or Ctrl+C is not registered until another peer connects to the listener.

Steps to reproduce:

1. Start smaug listener using ./meisc.py -m smaug -lp 8888
2. Hit Ctrl+C
   Expected result:
   The application should quit
   Actual result:
   Nothing happens until a connection is established to the listening port. After the connection is established the KeyboardInterrup is thrown.
