IIRC, (from doing the same thing :) ), it's really easy to get  
file_source to read invalid float/double values and get a bunch of  
NaNs in the input.

Is it worth the overhead of checking every single read for this?  
Probably not. But maybe we should do something about it... add an  
option for instance. Or more graceful handling of NaNs in some of the  
processing blocks.
