[wildfly-dev] timer service for extension modules?

My extension module creates a (MSC) service that needs to get periodic timer callbacks to clean up cruft that accumulates while it is being used by a deployed application. I could create a java.util.Timer when the service is created and cancel it when the service is removed, but I’m wondering of there already a timer service that I should be using for this sort of thing. Thanks for any tips or guidance, carl
