It seems a bit strange to have all the rb_free_recursive support and not
use it anywhere ... and a freefunc callback even, whose only caller
seems to set as null currently. Hmm, even in the knngist patch the
rb_freefunc stuff is unused. How do we now that it works?
(What, for example, if we were to allocate multiple nodes in a single
palloc chunk? I'm not familiar with this stuff but that seems
plausible)
