Indeed, synchronous call is implemented by invoking wait() in the caller thread in order to wait for the server response. > In this JIRA, we change ipc.Client to support asynchronous mode. In asynchronous mode, it return once the request has been sent out but not wait for the response from the server. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
