I could adjust the logic of my algorithm so that it behaves exactly like that...
I implemented a variation of your algorithm

However I'm getting worse performance out of it compared to my other prototype on a dual core Pentium D on Windows. I also tried to separate the blocked readers and blocked writers and only unblock one writer at a time. No change in performance.
How does the original algorithm compare to yours? Also, how many reader/writer threads are you using, and how many writes do you perform on average, 'per-writer-thread', lets say every 3 or 4 seconds?
Maybe I've made a mistake somewhere. :-)
