*
* The convgetrpc seems dodgy, because we might be in
* the middle of an rpc, and what about the one that comes
* in later? It's all actually okay: convgetrpc is idempotent
* until rpcrespond is called, so if we're in the middle of an rpc,
* the first convgetrpc is a no-op, the rpcrespond sends back
* the needkey, and then the client repeats the rpc we're in
* the middle of. Otherwise, if we're not in the middle of an
* rpc, the first convgetrpc waits for one, we respond needkey,
* and then the second convgetrpc waits for another. Because
* there is no second response, eventually the caller will get
* around to asking for an rpc itself, at which point the already
* gotten rpc will be returned again.
