Public bug reported:

The help for the rpc_workers config option is:

    Number of RPC worker processes for service.  If not specified, the
    default is equal to half the number of API workers.

However, this does not accurately describe the current behaviour, which
is to default to half the _default_ number of API workers.  This can
make a big difference; for example on a 256-CPU machine with 256GB of
RAM which has api_workers configured to 8 but rpc_workers not configured
to anything, this will result in 64 RPC workers, which is 8 for every
API worker!
