Well sure you could do that. But I don't believe that reading say 50 bytes at a time is very efficient even when you factor in automatic syscall batching. But

Well sure you could do that. But I don't believe that reading say 50 bytes at a time is very efficient even when you factor in automatic syscall batching. But this is all speculation. I didn't any consideration for this problem in the paper at all so I don't have the impression it was on the researchers' radar.
