The per-stream `Assembler` retains out-of-order received STREAM data until a contiguous prefix can be delivered; a peer sending many small STREAM fragments at gapped (non-contiguous) offsets forces un-coalescible entries whose per-fragment overhead grows without bound while never becoming deliverable.
