Detailed Description

Invariant:

Available memory addresses will be sorted w.r.t. their starting positions

At least one element exists in the freelist at any time.

Defragment on the fly: at any time, NO two consecutive chunks with chunk1.endaddr equals chunk2.begaddr exist

void MemoryPool::dealloc	(	void *	base,

defragment on the fly by attaching to the previous chunk if prevchunk.endaddr equals newitem.beginaddr, or by attaching to the next available chunk if newitem.endaddr equals nextchunk.begaddr

check the next chunk to see if we perfectly fill the hole

Insert x before pos: 'iterator insert(iterator pos, const T& x)'
