Well, from your other responses it sounded like you are including code/data structure/functionality only when they are used. So, I wasn't clear if this is missed out on cleanup or really part of UBC.
Besides, if this is needed only for a specific controller, shouldn't the controller worry about maintaining it ?

IMO, fork_cb/exec_cb doesn't convey the real meaning of the usage. > > Kirill > > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
