I have been testing 1+2,1+2+3 as well as 3+4 and have been of the
assumption that 3+4 does help ... I have now been runing a modified
version of 4 which prints a warning instead of doing anything ... I
have now seen the allocation issue again without the warning being
printed. So in other words

1+2+3 make the problem less severe, but do not solve it
4 seems to be a red hering.
