This is not an appropriate customization point for indirect_streambuf. The
correct way to customize the buffering policy would be through a template
parameter. Even better, if you can show that your implementation is superior to
the current one, I can simply use yours instead.

I'll have to review the old messages to remember what the sticking points were.
I seem to remember there was a problem with STLPort requiring a larger putback
buffer than other libraries.

It means that you can currently do whatever you would be able to do if I made it
protected.

Of course ;-) What else can you do with a void*?
