Yes it could be. As I understand it, regular file writes (not O_DIRECT) are only to the page cache and only block when there is memory pressure (so it is more of a throttle).
Reads, on the other hand, could be quite handy. What might be very cool is if there were a way to mmap and start faulting in the pages in the background, and get notified as they complete - or when all the faulting is done.
