No.  A font object is recorded in FONT_OBJLIST_INDEX of a
font-entity.

The strategy is to record all font-objects in font-entities, and
record all font-entities in a cache of each font-backend.  The caches
are freed when `delete-frame' calls font_update_drivers with
new_drivers as nil through this calling sequence.

font_update_drivers -> font_finish_cache -> font_clear_cache

At that time all font-entities and font-obects are freed.

If there's a memory leak for font objectes, it means that there is a
bug at some code implementing the above strategy.

I don't have a time to tackle this problem at the moment,
but I'll take care of it as soon as possible.
