I just checked. If I don't have read permissions, I am not able to open 
the file. When I open a file and change permissions afterwards, I can read 
the complete file alright. (Checked with a 4mb file, I hope that's beyond 
buffering.) So I guess permissions are only checked when you open the 
file.
