  FWIW, your program finishes just fine for me,
using AMD's CPU CL and
 Intel's most recent '2012' CPU CL package. I don't have their version
 1.5 around any more, but if there was a hang with that version, I'd
 imagine that would have been a bug that they've resolved.  
 I just removed Intel's 1.5 SDK and replaced it with 2012, and removed
 and rebuilt PyOpenCL. I still have this hang.

 I'm not sure what else to try next. 
Can you strace that program, see what it's doing when it hangs?
