Comment (by Chris Jerdonek):
> Why do you think that we should raise an error in this case?
It's not that an error should be raised from nothing. It's that
`ValueError` should be raised instead of `LibraryValueNotFoundException`.
If you look at the links to the code I provided, the `delta < 0` code path
isn't inside the try-except block a line later where that conversion takes
place for the `delta >= 0` case. Please look, and you will see what I
mean. This would just affect backends that derive from
`BaseMemcachedCache`.
