-   Since no alignment guarantees are made about the initial value returned
-   by sbrk, test the initial value and (if necessary) sbrk enough additional
-   memory to start off with alignment to BLOCKSIZE.  We actually only need
-   it aligned to an alignment suitable for any object, so this is overkill.
-   But at most it wastes just part of one BLOCKSIZE chunk of memory and
-   minimizes portability problems by avoiding us having to figure out
-   what the actual minimal alignment is.  The rest of the malloc code
-   avoids this as well, by always aligning to the minimum of the requested
-   size rounded up to a power of two, or to BLOCKSIZE.
-
-   Note that we are going to use some memory starting at this initial sbrk
-   address for the sbrk region malloc descriptor, which is a struct, so the
-   base address must be suitably aligned. */
