If a FatalError occurs before the server finishes launching, it will
not have drained the launchd-owned DISPLAY socket, so launchd will
just relaunch it. This can cause the server to crash in a tight loop
which will spam the user with CrashReporter windows that claim focus on
appearance.
This allows users stuck in this loop to "deal" with the problem without
popping up a crash report every 10 seconds.
