Somehow, the code for passing a daemon's parent was accidentally removed, thus breaking the tree-spawn callback sequence and causing all daemons to phone directly home. Note that this is noticeably slower than no-tree-spawn for small clusters where directly ssh launch of the child daemons from the HNP doesn't overload the available file descriptors.
