As far as I see, `context` shouldn't be const.

You cast a const `this` to non-const void* and then "back" to non-const 
UserIOStream. Then doWriteBytes is called on this seemingly mutable 
object that's actually const.

If I implement doWriteBytes in a way that mutates the object, I'm 
violating const.
