Assigning a builtin_function pointer into an intrusive_ptr increments
the reference count. (gettersettter refcnt = 1)

One of the effects of init_property() (in GetterSetter, specifically)
is to increase the reference count by one. (gettersetter refcnt = 2)

Function scope ends; due to the intrusive_ptr going out of scope, the
reference count is decremented. (gettersetter refcnt = 1)

gettersetter will not be destroyed until its owner (PropertyList)
decides to do so.
