Okay. I may be wrong, but it seems to me that the majority of Linux applications (probably excepting database packages and such) rely on the filesystem to eventually get their data to disk without them doing anything besides open, write and close operations.

No. I'm saying that an application that closes or flushes all of its open files and then tells the filesystem "commit the filesystem to disk" (e.g. sync) is then at a known point with respect to the dasd. It is free at that point to kick off a flashcopy via some command or utility and start running again.
