As long as the exceptions are declared within the RPC description, like
for instance this one:
GENODE_RPC_THROW(Rpc_create, Capability<Region_map>, create,
GENODE_TYPE_LIST(Out_of_metadata), size_t);
those kind of exceptions are caught in the server loop, and the server
will immediately reply with an appropriated error code, which is
detected on the client side and again reconverted into a C++ exception.
So yes: "the RPC call just end as soon as the error is thrown, allowing
the server and the session to continue normally" as long as it is an
exception expected by the RPC interface.
