Pre shutdown hook

[Juan Rivera]

Has anybody consider providing a hook to be called right before shutting down the server?   This is the scenario: A module creates a thread during initialization and then you want to close the thread during shutdown.   I figured this could be done by registering a destroy function in a pool, but I'm not sure if this is the right way to do it (architecturally speaking).   If there are initialization hooks why don't we have clean up hooks? Or are the pool destroy functions the designed way to do this?   Juan
