Yes, sure.  But, I think that in many ways what was being asked about
and expected was the sort of behavior that OS threads implementations
provide.  In particular, that an IO does not block _the program_, only
the task.  From this perspective, while it might not matter wrt to the
correctness of the program if this is true, it definitely matters wrt
to the user of the program and its intended use and possibily even its
usability.  So, whether it "matters" is not simply an issue of
"correctness"...
