Class (inherits from RuntimeException)

Represents an exception that is not necessarily caused by programmer error but rather something from the OS. A good example is trying to write to a read-only file. Checking the writability in advance introduces a 'time of check to time of use' race condition, so the correct thing actually is to just open it.
