A nonvolatile memory system, a nonvolatile memory controller and a method for assuring retention are disclosed. The nonvolatile memory controller includes a retention monitor that stores test characteristics corresponding to a use case and determines, each time that a read of a codeword is performed, whether the number of errors in the codeword exceed a retention threshold. If the number of errors in the codeword exceed the retention threshold, the block containing the codeword is retired. The retention monitor performs retention tests during the operation of the memory controller and adjusts the retention threshold when the results of the retention tests indicate deviation from the test characteristics corresponding to a use case.

One embodiment of an event management system, operating on a computer system having event producers and event consumers, includes an initial event handler program and an event queue having a first event. The initial event handler program retrieves the first event from the event queue for event processing. This event processing returns a first response to the initial event handler program, wherein the initial event handler program manages the first event on the event queue based on the first response.
