Hrmpf. It's a silent API breakage. The author intended to email us about
it, but apparently forgot. One now needs to increment a string-pool
refcount. The reason that didn't trigger a reliable crash is that
there's a path where the refcount of string-pool entries aren't asserted
to be above before decrementing the refcount... And that there
practically never are references to the pool entries after use.

Continuing to discusss whether there's a better way to deal with this.
