[sr-dev] question on RPC script reload: how is it invoked in the workers?

Hi list, I am looking at the python script reload functionality exposed by the rpc command "app_python.reload" and implemented by the function app_python_rpc_reload. The implementation increments a version number and calls apy_reload_script(). But it looks like apy_reload_script() would be run invoked in the process where the RPC server lives rather than the children. How is it sent to the workers for invocation? I think I am misunderstanding how the RPC server works: how do you differentiate between RPC functions meant to be executed by the master vs sent to all the slaves? Thanks Anthony
