> Components: platforms

> Priority: Major

> Fix For: 2.4

>
> {{GetAll}} and query cursors do not use {{BinaryReader.DetachNext}}. So in
> binary mode for each binary object in a stream we copy entire stream content,
> see {{BinaryReader.ReadAsBinary}}, which calls {{Stream.GetArray()}}, which
> causes copying in {{PlatformMemoryStream}}.
