That was a typo in my posting. I in fact did use pthread_detach; the line got deleted as I was composing my email. 

>So it reached a steady state after 5 loops. 

That was my problem. I only tested for 3 or 4 iterations; I should have when a few more times and I would have observed this steady. I just verified this with my own app. 

Thanks for helping me solve this mystery...
