// This holder must be wrapped around any code that opens an IL image.
// It will verify that the actual fingerprint doesn't conflict with the stored
// assumptions in the PEFingerprint. (If it does, the holder constructor throws
// a torn state exception.)
//
// It is a holder because it needs to keep a file handle open to prevent
// anyone from overwriting the IL after the check has been done. Once
// you've opened the "real" handle to the IL (i.e. LoadLibrary/CreateFile),
// you can safely destruct the holder.
