99% gone. The remaining 1% is refill_freelist(). If I use flush_dirty_buffers() there instead of waiting, I have no more semaphore timeouts (so far.. not thoroughly pounded upon). Without that change, I still take hits. (in my tinker tree, I usually make a 'small flush' mode for flush_dirty_buffers() to do that)
Feel is _vastly_ improved.
