description: >
  Disable mark-and-sweep and use only reference counting for garbage
  collection.  This reduces code footprint and eliminates garbage collection
  pauses, but objects participating in unreachable reference cycles won't be
  collected until the Duktape heap is destroyed.  In particular, function
  instances won't be collected because they're always in a reference cycle
  with their default prototype object.  Unreachable objects are collected if
  you break reference cycles manually (and are always freed when a heap is
  destroyed).
