Comment (by jinmei):

 Replying to [comment:11 muks]:
 > It was only the left-child's fission case that needed an additional
 test. It has been added now. The others are covered by the rest of the
 tests.

 It mostly looks okay, except the documentation should also be updated.
 I've committed a suggested change.  If you're okay with it, please
 merge.

 p.s. Please don't forget merging this change to memory/domaintree.h
 when it's ready.

 p.p.s. please consider picking up an open review request before
 proceeding to yet another development task.  From a quick look #2136
 has been open for quite some time.
