"""A simple load tester for WebSocket clients.

A client program sends a message formatted as "<time> <count> <message>" to
this handler. This handler starts sending total <count> WebSocket messages
containing <message> every <time> seconds. <time> can be a floating point
value. <count> must be an integer value.
