Although GNU/Linux doesn't have O_SEQUENTIAL, it has somewhat similar flags (e.g., madvise with MADV_SEQUENTIAL). I've tried using these flags in the past and came up empty: they complicate the code and sometimes make things faster and sometimes slower and it wasn't worth the maintenance trouble to tease things out.
I expect that Microsoft's O_SEQUENTIAL flag is similar. Besides, MS-Windows is relatively low priority for us.
