+	// In vanilla we did `CheckExitRules()` after each frag,
+	// which there can be multiple of when dealing with e.g. splash damage.
+	// And the order in which players get killed is not well-defined:
+	// e.g. for `G_RadiusDamage` and telefrag, kills get performed
+	// in the order returned from `trap_EntitiesInBox`;
+	// for the shotgun each pellet deals damage by itself,
+	// and the order is random;
+	// for the railgun the closest enemy gets damaged first.
+	// That resulted in inconsistent rules when there is one frag left
+	// and someone frags both a enemy and themself (or a teammate):
+	// if the enemy is processed first then the attacker wins.
+	// If a teammate is processed first then the game continues.
+	// Let's fix this by only doing `CheckExitRules()`
+	// when we're done processing the command.
+	//
+	// Note that this new behavior can result in e.g. two players
+	// hitting the frag limit at the same time.
+	// This can happen with missiles, which we run in `G_RunFrame()`.
+	// In such a case `ScoreIsTied()` will kick in, and the game will continue
+	// until the score gets untied, so this new behavior doesn't introduce
+	// a "multiple winners" situation.
+	//
+	// One might argue that in case of two missiles exploding on the same frame,
+	// the old behavoir is more fair, because `G_RunMissile()` is run
+	// in the order in which the missiles were created,
+	// so whoever shot first should win.
+	// However, this isn't entirely obviously fair,
+	// because two missiles can explode on the same frame
+	// even if they were shot a long time apart.
+	// For example, grenade launcher vs rocket launcher.
+	// In this case let's just tie the score.
