Interesting, thanks for trying to narrow it down.  I don't see anything on 
re-review that would cause huge increases in the amount of memory used, 
though the additional alignment we apply in that patch will increase things 
somewhat, so might make the problem happen faster.  Are you using UXA or EXA?
