The problem lies, as I understand it (ask Feldman for details) in that a find(1) or similar process will cause a lot of work to be done in kernel space, which means the scheduler is not going to clamp down on it. Also, it apparently hogs buffercache and I/O bandwidth. Changing these VOPs to be incremental would solve the problem.
