Say, once every 2 seconds, which is what most of those silly DOS caches do. Of course, you'll kill write performance for things that change a lot, like directories when you're unpacking a "tar" or "cpio" archive, but the filesystem will be "safer". If you can stand horrible DOS-like disk write performance, that's probably the right thing to do.
