When hitting ctrl+c a bunch of things happen within opsdroid to gracefully shut down the process.

My guess here would be that something is taking a long time to shut down.

It seems like the signal handlers are attached differently in windows (or not at all). This may explain some of what is happening here. https://github.com/opsdroid/opsdroid/blob/master/opsdroid/core.py#L53

For some updates of windows,ctrl+c wont eliminate windows.
