Description

In a simple client-server model the gateway constitutes the client, which will generally have to allocate some resources to communicate with the server.

There is however currently no way for a user to close a gateway, hence these resources will generally leak (unless the underlying RPC implementation either magically fixes that somehow or doesn't allocate resources for clients in the first place).
