Details 
This is also with the Obama test case, and 8 stylo threads.

tot-alloc:   2,770,560 in 4,329 blocks (avg size 640.00)
deaths:      4,329, at avg age 17,893 (0.00% of prog lifetime)
acc-ratios:  0.00 rd, 0.00 wr  (102 b-read, 216 b-written)

The blocks both die very young (17893 insns) and are almost 
completely unused.  According to the detailed access counts, none of
them have been accessed after offset 35, despite being 640 bytes
in size.

I think this is the same issue as bug 1364952, which is on central now. Can you retest both?
