Subject: [PATCH] Do not send request if server is down

Do not send an "event_notification" request in OnFileReadyToParse
function if server process is terminated. Otherwise, it blocks Vim
for one second or results in a traceback each time the InsertLeave,
CursorMoved, CursorHold, and BufferVisit events are triggered.
