I'd tend to agree. :) Moreover, I don't think fread/fwrite are 
guaranteed to work as you would expect with non-blocking file 
descriptors. So, providing a setblocking() call to files would require 
calling read/write instead of fread/fwrite in all the file methods, at 
least when in non-blocking mode. I don't think that's a good idea.
