If that’s not how it works, then how can you serve a client from more than 
one member of the worker pool?

No, but the shared-memory context can contain an index into a table of 
socket descriptors in private per-process memory. If the process trying to 
server a client context does not actually have a socket descriptor in the 
slot for that context, it can ask for one.
