End-of-file on stdin is not detected on Mac OS

[sgjesse]

rUNNING the following program with dart_bin on Mac OS does not terminate when Ctrl-D is pressed.

void main() {
  stdin.dataHandler = () => stderr.write(stdin.read());
}

On Linux and Windows it does terminate.

On Linux Ctrl-D is detected by POLLIN event with 0 bytes available when the filedescriptor is stdin and it is connected to a terminal.

On Mac OS however Ctrl-D is reported as a character by POLLIN and when checking ioctl for available bytes. However when read is actually called Ctrl-D is not read an one less character than expected is read.
