Gaurav Saini commented on TINKERPOP-1886:
-----------------------------------------
[~spmallette], loop.run_sync executes the passed function and then it closes.
The WebSocketClientConnection object which is returned by
websocket.websocket_connect makes use of PeriodicCallback which in turn makes
use of the IOLoop to schedule ping requests. Since your loop would close as
soon as the WebSocketClientConnection object is returned, there are no pings
scheduled.
