+      // Set up stdin to be the pipe, infd[0] is our reading end.
+      close(STDIN_FILENO);
----------------
This might be a bit more readable:

`// infd[0] is the child's reading end.
close(infd[1]);`

`// Setup stdin to serve as the infd pipe.
close(STDIN_FILENO);
CHECK_GE(dup2(infd[0], STDIN_FILENO), 0);
close(infd[0]);`
