I pulled the patch into 3.2-rt and 3.4-rt. I can > remove it if you think it's not necessary and will cause a slight > performance penalty. I took it out of 3.2-rt as I needed to add a patch and rerun my tests. But I'll leave it in 3.4-rt (unless you think I shoudn't) just so I don't need to rerun the tests. I'm only posting a pre-release anyway. Thanks, -- Steve
