I don't know whether File.read is actually written in terms of
File.open (I'm afraid I'm too lazy to check right now), but I think
the underlying system calls etc. would be at least very similar. I
expect File.read is slightly cheaper, since it doesn't involve the
whole block structure. (I'm talking, of course, specifically about
comparison with File.open {|f| f.read }, where you get the whole file
at once.)
