Even if we do have a Z:\ drive, we'd have to decide between C:\ and Z:\ 
paths. I suppose it could just notify on every equivalent path, 
defaulting to just using the unix pidl if Z:\ doesn't exist.

That's a good point actually. In the Microsoft docs(1), 
SHCNRF_InterruptLevel mentions notificatiosn from the *file system* as 
opposed to the *shell*. Perhaps it'd make sense for 
shell32/changenotify.c to listen for filesystem events, and dish out 
shell notifications to listeners with that flag. I'll do some testing 
on Windows to see if my interpretation of the docs is correct. Does 
that sound like a better way to approach this?
