Thanks for the contribution. I think the general idea is good, but I think
the implementation can be improved. How about changing
`CopyOnWriteStateTable::snapshotTableArrays()` in such ways that the returned
snapshot array is already created with a size of
`max(whateverTheCurrentCodeDoes, size())`. This prevents that we ever have to
create another array, in particular in this corner case where we are dealing
with huge arrays. Then the remaining code should automagically work without
further changes. Adding some nice comment might help that our optimized
snapshotting algorithm assumes that the array can hold the flattened entries.
What do you think?
