I have had rpm lock up on me a few times. I think it was waiting on a 
sempahore or some other synchronization event. After killing the process 
(after several hours) no rpm transactions could be completed, they all 
hanged at the same point. The only way to get rpm to work again was to 
reboot the system. 

Not sure if it is related or not though. I never thought to try it as 
non-root.
