No. POSIX allows the default to be line buffered (or to be buffered in
other ways, so long as it's not "fully buffered"), and some platforms do
that. (POSIX also allows the default to be unbuffered, but it doesn't
require this.)
We really don't want stderr to be unbuffered on GNU/Linux and similar
platforms; that would slow down execution signficantly.
