This isn't a software solution, but bumping up your RAM could buy you  
a lot. I don't know what kind of caching you're doing, but more ram  
gives you room for (more) query_cache, which is a little thing that  
can buy you a lot. IME, once MySQL runs out of ram, the read/write  
temps can bring you to a crawl, and then the queries just pile up.  
RAM is cheap. Even after you optimize your code, that headroom can  
help performance.
