See attached vminfo, which shows just a small heap starting from
0x8170000 (0x8048000 is the program itself and 0x8170000 is its data)
and ending with

0x8698000[0x7aa8000] (prot=0, max_prot=RWX, offs=0x528000)

Which is the 128MiB pre-reservation.

There are a few big chunks which I don't know what they are:

 0x2b60000[0x600000] (prot=RW, max_prot=RWX, mem_obj=2505)
 0x4a60000[0x35e0000] (prot=RW, max_prot=RWX, mem_obj=2507)
0x10140000[0x10000000] (prot=RW, inherit=none, mem_obj=2567)
0x20140000[0x2aa0000] (prot=RW, max_prot=RWX, mem_obj=2568)
