I had a similar problem (serialising NaNs - it turned out I had 
accidentally left some of my variables uninitialised), and there was a 
big discussion about serialising NaNs and infinities about a year or so 
ago. I seem to remember that the outcome was this could not be supported 
across all platforms, although I could be wrong.

Could someone point this discussion out in the archives?
