Plus, [de]serialization often needs to be done under GIL (although under non-shared GIL per process, it interferes with any other async thing that may be done in each process). It also screws up C extensions that don't support fork and does not solve the problem of increasing TLS handshake/fanout in outbound requests by the number of cores. The whole thing sucks in production.
