In this case (memory wasting) it looks as a bad idea, but on the other hand
this malloc algorithm is much more faster then the allgorithms used by
other commercial allgorithms. BTW it's come from the U*IX world, lota U*IX
(f.e Linux) uses this, 'cos it's fast and works well with page swapping...
Check out the malloc source code in libc, there are tons of comments about
it.
