ensure clean exit on KeyboardInterrupt

[johnnykv]

If SIGINT is thrown it does not get handled properly.

 Traceback (most recent call last):

KeyboardInterrupt

Heh, that worked for me...

[glaslos]

Doesn't this work?

try:
    main()
except KeyboardInterrupt:
    print "bye"

That would work yes, but i would like to ensure that the greenlets has a all nice and cosy shutdown.
Just figured the problem... committing now...
