int64_t	get_size () const override
	Get the size of the file, or -1 if it is unknown.

size_t	pread (char *buffer, size_t size, int64_t offset) const override
	Read a range of bytes.

void	pwrite (const char *buffer, size_t size, int64_t offset) override
	Write a range of bytes. Extend file size if necessary.

void	sync () override
	Write data durably (including file-size change)

void	shared_lock (int64_t start, int64_t size) override
	Lock a range of bytes for reading (prevents writes, not reads)
