Persuasively argued. You appear to have your wish, as this patch was merged in -pre5.
A `dirsync' option does make sense though, for the reasons which Stephen outlined.
The whole handling of synchronous operations needs a rip-up-and-rewrite anyway. We're currently holding onto a stack of locks while waiting for the disk to spin round and round. It's a great scalability bottleneck for multiple threads doing things in the same directory. This is something I shall look at when the kernel versions turn odd.
