stderr is unbuffered by default, but stdout is line buffered if the
output is the screen or *block* buffered if the output is a file
(i.e. redirected).  The only way to avoid this is to use one of the
buffer-setting functions (setbuf, setbuffer, setvbuf) to change the
output buffering of stderr and/or stdout.
