Amylaar-LPMud uses a Mark&Sweep collector in addition to the
reference counting. However, since this collector was added very
late in the development, it suffers from lack of integration into
the overall design: for example each collector run swaps in all
swapped-out objects in order to trace the pointers.

Consequently the collector is run (from the backend loop) only when
the driver had to tap into the memory reserves, or when the LPC code
instructed it.
