I've got an APP at work that will need to be working on RH5 and possibly
Centos 5 that uses gettid(), so I'm going to hang onto your posting just

I will be (and Centos, too, once it comes out). 

Thanks for the heads-up.

                         While we were still sinners, 
                              Christ died for us.
