MALLOC:   ------------
MALLOC: =    150790144 (  143.8 MiB) Actual memory used (physical + swap)
MALLOC: +            0 (    0.0 MiB) Bytes released to OS (aka unmapped)
MALLOC:   ------------
MALLOC: =    150790144 (  143.8 MiB) Virtual address space used
MALLOC:
MALLOC:           4615              Spans in use
MALLOC:            145              Thread heaps in use

------------------------------------------------
Call ReleaseFreeMemory() to release freelist memory to the OS (via madvise()).
Bytes released to the OS take up virtual address space but no physical memory.
