--- Comment #4 from Marshall Clow (home) <mclow.lists at gmail.com> ---
The LWG issue was closed as "Not a defect", and the discussion decided that the
standard gives no guarantees about which underlying functions are called, and
when.

In particular, the point was made that there was no requirement to call sputn
from osgtream::write - that repeated calls to sputc would be just as correct. 
(though probably not as efficient).

Closing as INVALID.
