One CPython interpreter caps sustained segment throughput at ~160 MB/s; spawned children each run the existing thread-pool path on a contiguous chunk of the batch, reaching NIC line rate on fast CDNs. Opt-in via --download-processes (default 1), engaged only for 24+ segment batches. Sessions are rebuilt per child from a picklable spec; RnetSession falls back to a single process when it has no impersonate preset.
