.. master:: void quota_demon(void)

  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, :master:`slow_shut_down` will be called to start Armageddon.

  Up to now, the wizlist lacks various information needed to detect the memory-hungriest users.
