Intended for future use to implement util/file/file_writer. There's a similar class in base: https://code.google.com/p/chromium/codesearch#chromium/src/base/win/scoped_handle.h&l=28 However (perhaps for historical reasons) it does not distinguish between the possible types of HANDLEs which have different invalid values, resulting in a need to copy a bunch of code rather than simply using ScopedGeneric. Instead, distinguish between the types so the caller can use the correct one.
