+SYNOPSIS
+	void quota_demon(void)
+
+DESCRIPTION
+	Handle quotas in times of memory shortage.
+
+	This function is called during the final phase of a garbage
+	collection if the reserved user area couldn't be reallocated.
+	This function (or a called demon) has now the opportunity to
+	remove some (still active) objects from the system. If this does
+	not free enough memory to reallocate the user reserve,
+	slow_shut_down() will be called to start Armageddon.
+
+	Up to now, the wizlist lacks various informations needed to
+	detect the memory-hungriest users.
