It is best not make such assumptions.
Polling is often necessary, if there is no built in
way to do an equivalent blocking operation. It is also
sometimes necessary in real time systems because it
can be much faster than yielding and being resumed by the OS.
In particular, it can be much faster than
a hardware interrupt (forget the OS!).
