3 - In singleton(), do a check whether class was sent in. There was a shifting
4 issue if called with IPC::Shareable::singleton() as opposed to
5 IPC::Shareable->singleton()
6 - When an exclusive collision occurs and both 'graceful' and 'warn' are set,
7 the warning thrown now includes the segment/semaphore key in use. This
8 makes it easier to clean things up with 'ipcrm'
