Yes, that is correct.  The current draft was intended to be a small 
change.  Directly catching these cases would require some sort of 
exception handling facility, which we thought would be outside the scope 
of the TS.   While it is certainly possible the devise a case where a 
code would deadlock in a situation like this (which is no change from 
the current F2008 situation), there would be cases where other images 
could continue to a statement that did have a STAT= and detect that an 
image had failed.

Cheers,
Bill
