The spec does not mandate buffer limits for tee(). And to be fair, the spec allows implementations to implement the actual internal mechanisms for tee()and other APIs in any way they see fit so long as the observable normative requirements of the specification are met.

According to Dell, its engineers say that “a small batch of early XPS units” have the quick typing issue I ran into. They also say the issue is currently resolved and doesn’t affect XPS units shipping now. The company plans to release a firmware fix later this month, and I’ll be sure to update this review once I get my hands on it.
