A talloc pool is a chunk of memory that can be used as a context for further talloc calls. Allocations with the pool as the parent just chew from that memory by incrementing a pointer. If the talloc pool is full, then we fall back to the normal system-level malloc(3) to get memory. The use case for talloc pools is the transient memory that is used for handling a single SMB request. Incrementing a pointer will be way faster than any malloc implementation. There is a downside of this: If you use talloc_steal() to move something out of the pool, the whole pool memory is kept around until the last object inside the pool is freed. So if you talloc_free() the pool, it might happen that the memory is freed later. So don't hang anything off a talloc pool that should live long.
