I think over it again, the content of the `sharedBuffer` make difference
to the result of the `getEventsForPattern`, so the result should be update
with the change of the `sharedBuffer`. But i think we only have to reset the
`shouldUpdate` flag to `true` here rather than create a context again, right?
