Regions and collections

Where values live and how they are kept: homogeneous collections and pools, and the regions that hold many kinds.

Homogeneous: collections, pools and buffers

• collections: A growable list, an owned string, dictionaries, a set, a double-ended queue and a column-per-field SoaList.
• pool: A generational pool: values of one type in slots, handed back as Refs that go stale when the slot is reused.
• pools: Sets of records that holders elsewhere name by a handle; GenPool[T] is the default kind.
• slots: A compatibility shim: SlotTable and Slot are now aliases for pools' GenPool and Handle.
• iobuf: Owned buffers for I/O, lent to an operation by moving them.
• bufpool: The buffer pool: a static region of power-of-two buffers.

Heterogeneous: arenas, reference counting and garbage collection

• arena: A dynamic region: values allocated one after another and freed all together, finalizers newest first.
• rcweak: Reference counting with weak references, beside core's Rc.
• collector: Gc, a garbage-collected region, and its collector.
