/**
* Returns (by copy) a struct containing various summary statistics:
*
* arena: current total non-mmapped bytes allocated from system
* ordblks: the number of free chunks
* smblks: always zero.
* hblks: current number of mmapped regions
* hblkhd: total bytes held in mmapped regions
* usmblks: the maximum total allocated space. This will be greater
* than current total if trimming has occurred.
* fsmblks: always zero
* uordblks: current total allocated space (normal or mmapped)
* fordblks: total free space
* keepcost: the maximum number of bytes that could ideally be released
* back to system via malloc_trim. ("ideally" means that
* it ignores page restrictions etc.)
