[Insight-users] Thread safety of itkMultiThreader : Aborting filter execution

[Hannu Helminen]

Luis & James,

The idea of having the progress reporter contain an abort flag seems a very 
good one. At least I would welcome this change, it would make my life much 
easier.

But please do not forget my original hope of making the multithreader more 
robust. Of course one could be careful never to throw any exceptions from 
within ThreadedGenerateData(). But I feel that exception safety is always a 
good goal to have, and in this case it could be relatively easily achieved. 
ITK is already almost everywhere exception safe.
