/* Using the now commented out statements in checkConnection(), I watched how
* many ticks disconnects-after-initial-connect lasted. Out of roughly 15 trials,
* 5 disconnected; 4 were DCd for less than 20 ticks, while the 5th was ~50 ticks.
* So I set the tolerance here at 25, and initial DCs should be very rare now.
* This should be able to go to 50 or 100 without affecting legitimate disconnects'
* downtime, but lets be conservative for now.
