shared_array_buffers grows via repeated push_back() while iterating shared_array_buffers_, even though shared_array_buffers_.size() is already known before the loop starts and is an exact count of how many items will be pushed (one per iteration, unconditionally). This reserves capacity upfront to avoid the repeated allocate/copy/ free cycle that happens each time capacity is exceeded, mirroring the existing array_buffers.reserve() in the sibling Message::Serialize().
