Gregory Szorc 8e85824bcb Bug 1411462 - Abort when I/O error seen; r=glandium ... Before, I/O errors writing to stdout/stderr (e.g. due to broken pipe) would result in handleError() being called and execution would keep running. This would potentially result in an error message for every log/line failure being printed to stderr. We change the behavior so I/O failures are fatal and abort execution. We test the new behavior by changing a test to pipe to `head` directly. Since `head` exits once it has seen sufficient output, this results in an EPIPE which now results in immediate program termination.
