---------------------------------------+------------------------------------
 Can't quite figure out how, but creating a new instance of a Monitor (std
 ruby lib) creates an infinite loop which eventually falls over with stack
 too deep. Looks like it's maybe an issue calling super from within a
 mixin, when the mixin is within a class which has no explicit superclass?
