No, one generally doesn't. Why on earth would anyone bother with their own
low level memory allocation based on pages unless they were writing something
like a database? Plus I'm sure most modern implementations of malloc() are 
sophisticated enough not to just allocate random blocks of memory but have 
their own pool behind the scenes which they manage.
