// Class to enumerate volume labels of volumes assigned
// a drive letter under MSW.
// Also gets the full UNC path for drive-mapped network
// shares.

// Windows has this very exotic concept of drive letters (nowadays called
// volumes), even if the drive isn't mounted (in the sense of no media
// inserted).
// This can result in a long seek time if trying to enumerate the volume
// labels, especially with legacy floppy drives (why are people still using
// them?). Worse, even if no floppy drive is installed the BIOS can report
// one to exist and Windows dutifully displays A:

// Since the local directory tree including the drives is populated at
// startup, use a background thread to obtain the labels.
