I notice blkid can be very slow to show a new label

Sometime (possibly a few hours) after cloning a partition (with dd) and then renaming the target and giving it a new UUID (with tune2fs), I entered blkid to look at the labels. The list it displayed was obviously not up-to-date: sdb4 had the old label. I knew that was incorrect because thunar was already displaying the new label of sdb4.

Eventually, I entered blkid again, and finally saw Sdb4's new label listed. The label took, just after a rather long time. Is there anything I can do to improve on that? Something that would give the system a prod to notice the change faster?
