As the error message says, the problem occurs because another 
file is accessing it.

Some common culprits are:

- Anti-virus / security software, such as Windows Defender. 
Adding the directory containing the D code being reduced as an 
exception usually helps.
- File synchronization software, such as OneDrive / SyncThing.
- Editors/IDEs. Make sure the directory being reduced is not part 
of any project/solution open in Visual Studio etc.

I think I made Dustmite retry after a second when it gets that 
error. Is that not the case? Post the full output, if so.
