Peon 1.4.14

Server owners: this is the one to take. Everything from 1.4.9 to 1.4.13 could still take a server down, in two different ways.

The server stopped and stayed stopped. A cleanup routine removed entities while it was still walking the list it was removing them from. That corrupts the structure under the loop and throws inside the tick loop, so Minecraft writes a crash report and shuts down cleanly. Because the exit is clean, most service managers will not restart it, and players just get "Connection refused" until someone notices. The same routine also did a full sweep of every entity in the world on each call, and it is called from the tick loop. It now collects first and removes afterwards, and only does the heavy work once a minute.

The server froze for sixty seconds after every boot. The avenue that links all the plots was laid again from the first plot to the last on the first tick, forcing terrain generation kilometres from any player until the watchdog killed the server. It now remembers how far it reaches and only lays the new stretch. Five call sites did this; all five are fixed, and the full rebuild is reserved for an operator command.

Also since 1.4.9: a lag spike no longer reads as cheating to the rate guards, so honest players stop being kicked after a freeze; guard warnings expire instead of stacking all evening; login attempts are capped at three per address per minute; and three disconnect screens had their emblem redrawn.
