Although its a curiosity to just print the value of iostat when you use this 
error/condition capturing mechanism, the idea of it is to "handle" it, in which 
case one would not normally just go do another read.  The idea is to avoid doing 
another read that results in, formally speaking, undefined values.  Its really 
up to the programmer to deal with these situations, not the compiler or the run 
time library.
