Interesting to see what happens over the network on that - to windows
servers it looks like the 1st write at a high offset (at least for a
non-sparse file) causes huge delays - potentially causing the write to
timeout. From poking around with the NT IOCTs it looks like they have
not only the sparse bit that is a hint that most ranges are unallocated
(assumed zero) but useful calls to query the non-zero ranges. There is
probably a way to accomplish the same thing as you note.
