* Returns the maximum number of bytes obtained from the system. This
* value will be greater than current footprint if deallocated space has
* been reclaimed by the system. The peak number of bytes allocated by
* malloc, realloc etc., is less than this value. Unlike mallinfo, this
* function returns only a precomputed result, so can be called
* frequently to monitor memory consumption. Even if locks are otherwise
* defined, this function does not use them, so results might not be up
* to date.
