Ok so I have an application where I need to

Other than reading a few GB of data, is there a way to flush
out the cache copy of a file I've written?
possibilities include:
a file flag saying "don't keep a copy after it's written to disk"?
a syscall discard_cached_blocks(fd);
?
any other suggestions?

Hmm. That means you couldn't use a 'snapshot' to force the
issue, right? If you *could* use snapshots, you could close
the file, snapshot the partition, mount the snapshot, and
read the file from it's copy in the snapshot-filesystem.
