Are you open to putting some code in rack? If so, I'd try inserting a mutex as early in the request request cycle as possible and see whether you can repro the problem with the threading reduced as close to single-threaded as possible. If its a threading issue, you've got some real detective work ahead of you, but it sounds like you already know that.
Sorry not to be encouraging. We're using MRI and Mongrel -- but this is, I agree, an important problem.
