Hmmm what if this happens : say you want 16 byte alignment and you chunk
is 4096bytes so you get first pointer and it's 8bytes in the wrong
direction. Then when you allocate next chunk you'll get it again 8bytes in
he wrong direction and so on.
I think much simpler way is to allocate size+alignment-1 bytes and then
just increment the pointer so that it points to the aligned part. This
wastes a part of the memory though. If you want to free it later you can
just keep two pointers instead of one - one pointer you pass to free and
another that you pass to the whatever procedure that wants the memory.

PS If you really want to save memory and allocate exactly size bytes, then
you could use your procedure for example and if it doesn't work use mine
instead of returning NULL.
