Documentation

When pruning, try to prune back to this factor less than the maximum size.

In order to prevent constant pruning, we prune back to a number somewhat less than the maximum size. This option controls exactly how much less. For example, given a maximum size of
50000 and a prune factor of 0.1, the pruning process will try to
cut the registry back to (- 50000 (* 50000 0.1)) -> 45000 entries. The pruning process is constrained by the presence of
"precious" entries.

This variable was added, or its default value changed, in Emacs 25.1.
