PING packets are sent if the server takes longer than 1 second or so.
There are two interpretations of the delay:
1. The server is busy
2. The server died (or the connection went down).
Since it's not possible to know how long the processing will take, the
owserver sends a PING message if the data isn't ready within the 1 second or
so.
The client can ignore it, or set a timeout on reading the response of 2
seconds and if nothing arrives (PING or data), you have an error.
If the read takes a very long time, more than one PING might be sent.
