  • reference counting — (programming)   A garbage collection technique where each memory cell contains a count of the number of other cells which point to it.

Cells in such structures refer (indirectly) to themselves and so will never have a zero reference count. This means they would never be reclaimed, even when there are no references from outside the structure.
