Call fsync to be truly "fully persisted" #2

There should probably be a way to turn fsync on/off (currently always off). Without calling fsync, the data can be in a write cache and not reach the filesystem.

It's a correctness/performance tradeoff that you could let the user make.

Thanks for posting this! fsync is always enabled now. To disable it use flatfile(path, {fsync:false}.
