well, i have myself reproduced 30+ secs worth of pid-alloc related lockups on my box, so it's was definitely not a fata morgana, and the pid-allocation code was definitely quadratic near the PID-space saturation point.
There might be something else still biting your system, i'd really be interested in hearing more about it. What workload are you using to trigger it?
