I have spoken on the subject with Heikki couple of times, and simply put, this is not feasible. This change hardly made to 5.1. Some other nice enhancements are only in 5.2. These are, actually, quite drastic changes in the code and those are not doable in a stable release. A small note on the backporting of this enhancement to 5.0 and 4.1.

We always seem to have contention on our database, with locked tables, and we use all innodb tables with auto increment on just about every table. I guess we'll have to start debating if we move to 5.1.x. I definitely think this is one of our problems.

So I wonder why you say the patch for 5.0 is not worthwhile. Frankly, we had (and have right now one big) a lot of customers who are hurt by this problem. I believe MySQL Support has much more. So one option for them is the planning to upgrade to 5.1 ? Which even is not in production stage, and actually will be ready for production usage in about 6 month or more after 5.1 is officially released. James,

Go INNODB! It's nice to see these bugs FINALLY being fixed. The thread concurrency stuff in 5.1 looks awesome Now if we can just get the whole group commit thing sorted out. And Heikki.. please start assuming you're on 8 core boxes :) Sweet….. Go INNODB!
