Thanks. Do you have performance numbers? It sounds like your approach is
intended to give lower I/O response latencies, but Remus will give
better throughput with high I/O load as it doesn't sync on every single
outgoing I/O.

If both projects are indeed headed for the tree, people are going to
need some ideas of which to use...
