In all my years of using Windows, I have never seen or heard for 
this error message to lie (i.e. occur due to a reason different 
than what it states). I've also used junctions and symbolic links 
a lot.

It's possible the junction is confusing some software into not 
closing a file, though.

Sometimes, the reason can be really unobvious. We've ran into a 
similar problem a while ago on CI machines, which turned out to 
be the security software included with the then-new version of 
Windows. It doesn't hurt to check.

Probably trying to invoke Dustmite manually would be progress 
then, with the Visual D bug report aside.

1. DustMite will not touch anything outside the parent directory 
of the path you give it (though the test command might).
2. DustMite doesn't care about junctions and treats them as 
directories. When creating test copies of the source, it will 
recreate the directory structure with junctions replaced with 
directories.

FWIW, you can use Process Explorer (by Microsoft) or Process 
Hacker (FOSS) to find which processes hold handles to a file. 
That might provide a clue.

Yes, well known gotcha. std.file.dirEntries has a followSymlink 
parameter. DustMite uses the default (true).
