Comment (by rhaas):

 I just found that RotatingSymmetry90 also contains a reduction call (in
 rotatingsymmetry90.c line 175). However since it uses TAT/Slab it "can
 only be used if there is a single local component per MPI process" anyway.
 Also moving the affected lines outside into a LEVEL mode routine defeats
 an optimization to quit early if there is nothing to do and the routine in
 question is not a scheduled routine to begin with. It does however make
 runs with RotatingSymmetry90 produce very large log files (if -L3 is
 used).
