Out of memory occurred while running V8 benchmark several times in a row.
Garbage collection is not triggered and new blocks are added
because high water mark is big enough and overcommit is allowed by MAP_NORESERVE flag.
(MAP_NORESERVE is set when mmap is called)
It seems that this flag had been added for using both x86-64 and Fixed VM Pool together.
