The API was intended to be "blob friendly" (though it's not security
declaration friendly!), and I don't object to using blobs for new
instances or switching to blobs when modifying existing instances.

I suspect the most reasonable approach is to test
isinstance(self._data, str); it's self._data is a string, wrap it in a
StringIO for read-access, and replace it with a blob for write-access.
 The size property is affected as well (and I'd like the size to
continue to be cached on the instance, since that's used by the ISized
adapter commonly used for folder listings).
