Furthermore, there can be multiple XPCs...I still think the parent owning all the instances makes the most sense and for the child to have the same lifecycle as the parent. I'm not sure there is anything in the spec that forbids us from doing this. What we could do is, when the parent gets removed, pick a new "master" SFSB to hold the references to the other SFSB instances as well as the XPCs.
