Honestly, I really never thought of the issue of whether this would
push some structure over a power-of-two size.  It's not like either
Path or IndexPath have comments saying "for the love of heaven, don't
make this bigger".  This is in contrast to, say, PGXACT, where there
is a such a comment, because I knew it was an issue and I added a
comment explaining that issue.  Now maybe I should have foreseen the
objection anyway, but, you know, it's hard to foresee everything
somebody might object to.
