Matthew Dillon e4649cfac3 Change the write-behind code to take more care when starting ... async I/O's. The sequential read heuristic has been extended to cover writes as well. We continue to call cluster_write() normally, thus blocks in the file will still be reallocated for large (but still random) I/O's, but I/O will only be initiated for truely sequential writes. This solves a number of annoying situations, especially with DBM (hash method) writes, and also has the side effect of fixing a number of (stupid) benchmarks.
