That's not a good assumption. I think, eg. the JSO examples do not run in  
an infinite loop at all, they sleep after each poll if the previous poll  
didn't return anything. Not very common in Java but not a completly new  
technique either.

Granted, it's been a long time since I used JSO, and I can't say I was  
wild about this part of the design, but there's no real need this should  
take up any significant system resources. If it really *really* bothers  
you, and you like the API enough otherwise, consider writing a patch that  
handles things a little more elegant.
