WAT? The overhead is in issuing system calls, you'd want to do as

as possible. Reading byte by byte is an exemplar of idiocy in I/O code.
That's why we have things like byLine().
Which uses C's BUFFERED I/O and it reads from it byte by byte via getc.
Even though sys calls are amortized by C runtime, we have a function
call per byte. No wonder it's SLOW.
byLine doesn't use getc. -- Andrei
