Blocking I/O: What Is That?
===========================

A number of demo sessions that show what the term *"blocking"* is. *To
wait for an event - to block* is an important concept in operating
systems - it give the OS the chance to do other things like power
saving, or giving other processes the chance to run, while it does the
nasty things like interrupt management for us.
