-  often not) due to alignment and minimum size constraints.
-  You can use this many bytes without worrying about
-  overwriting other allocated objects. This is not a particularly great
-  programming practice. malloc_usable_size can be more useful in
-  debugging and assertions, for example:
-
-  p = malloc(n);

-  malloc_stats();
-  Prints on stderr the amount of space obtained from the system (both
-  via sbrk and mmap), the maximum amount (which may be more than
-  current if malloc_trim and/or munmap got called), and the current
-  number of bytes allocated via malloc (or realloc, etc) but not yet
-  freed. Note that this is the number of bytes allocated, not the
-  number requested. It will be larger than the number requested
-  because of alignment and bookkeeping overhead. Because it includes
-  alignment wastage as being in use, this figure may be greater than
-  zero even when no user-level chunks are allocated.
-
-  The reported current and maximum system memory can be inaccurate if
-  a program makes other calls to system memory allocation functions
-  (normally sbrk) outside of malloc.
-
-  malloc_stats prints only the most commonly interesting statistics.
-  More information can be obtained by calling mallinfo.
