is there a way to disable StringInterner?

[Randy Prager]

For debug logging we are using the toString() method on generated VOInterface objects but running into OOM errors.  Is there a way StringInterner can be surpressed?

The assumption is there should only be a small number of Bytes objects and thus a small number of StringInterner.  If this is using a lot of memory, I suspect you are doing something else unexpected.  We can change the code so it shouldn't matter as much if you have created a lot of Bytes objects.  We could also add a flag to disable the use of the StringInterner but I would make sure the rest of the code is efficient first.  Each Bytes object has a non-trivial overhead off heap, so you are better off creating a small number of these are reusing them.
