Not really, you can find the answer by a simple command... ;-)

iant:~/tmp/dolfin-0.5.0/src/kernel/mesh> grep initChildren
*MeshRefinement.cpp | sort | uniq

TetMeshRefinement.cpp:  cell.initChildren(1);
TetMeshRefinement.cpp:  cell.initChildren(2);
TetMeshRefinement.cpp:  cell.initChildren(3);
TetMeshRefinement.cpp:  cell.initChildren(4);
TetMeshRefinement.cpp:  cell.initChildren(8);

TriMeshRefinement.cpp:  cell.initChildren(1);
TriMeshRefinement.cpp:  cell.initChildren(2);
TriMeshRefinement.cpp:  cell.initChildren(3);
TriMeshRefinement.cpp:  cell.initChildren(4);

Note that the number of children is at least one for each cell.

PS: I send this to the mailing list in case someone else is interested.
