It is; it persists in 4.3BSD and 4.3BSD-tahoe; and there is no really
easy fix.  You can add your own flush for all line buffered streams:

	static
	flushifl(f)
		FILE *f;
	{

		if (f->_flag & _IOLBF)
			(void) fflush(f);
	}

	flushlb()
	{

		_fwalk(flushifl);
	}

_fwalk is undocumented, so this should be used only `#if needed' as
a workaround.
