drain.hpp is attached. If you compare it side-by-side with iostreams/copy.hpp, 
you will find that drain uses the copy_impl functions from copy.hpp, but 
reimplements the copy() functions as drain(), the one difference being not 
closing the sink (shown commented out in the source for visibility).

The code in copy.hpp could perhaps be modified to allow a simpler 
implementation of drain, but at the expense of extra complexity in the copy* 
templates. I went for the easier, non-invasive approach of just 
reimplementing the necessary functions in a seperate header file.
