I've noticed that my Cullen Prime Search (LLR) 6.09 task llrCUL_91107183_2 is regularly checkpointing once more some 5 minutes after being preempted (while it has previously checkpointed exactly at the preemption moment):

16.06.2011 10:17:18 | PrimeGrid | [task] task_state=EXECUTING for llrCUL_91107183_2 from start
16.06.2011 10:17:18 | PrimeGrid | Restarting task llrCUL_91107183_2 using llrCUL version 609

....

Is it a known and expected behavior (for some unknown reason), or some hidden error (sort of post-mortem spasms? :-)
