I do not think this is the right way to fix this. This sort of thing really makes for difficult to maintain and undercuts the functionality of the loader.

Instead, I think it would be better to place these classes into helper functions instead of gating them one by one.

@cachedout Is this one also good now?

[twangboy]

This one probably should have gone into the latest release

I'm not following the logic here. Why are we gating Windows-specific classes in functions but then leaving windows-specific imports at the global level? In my testing, Windows-specific exceptions are still thrown. I suspect we need to put these imports into a __virtual__ function.

I don't think this and winservice.py are even being used anymore. I think they were early attempts to create a Windows Service for the Salt-Minion. We should probably look at getting rid of them.
