Answer 1

What's wrong with your 2nd option but forcing it to read from stdin ? (Requires bash)

while true; do
  read
done < /dev/stdin

From man bash

Bash handles several filenames specially when they are used in redirections, as described in the following table:

          /dev/stdin
                 File descriptor 0 is duplicated.
