Adds OutOfMemory a standard exception signaled when the system is running out of memory. By default it calls signalLowSpace but since it is a subclass of error it will trigger proper exception handling in production environments (this avoids notifiers popping up on a server because an ill-formed request attempts to allocate a huge amount of memory).
