Hi. I put in some more probes, and it looks like the fonts aren't being
marked as used properly. I also wrote a bit of code to make the gc
actually free fonts it drops. Unsurprisingly, this causes things to
crash, since it then frees fonts that are actually in use. Does it make
sense to track down why the fonts aren't marked as used? If the
compaction code goes away, then it doesn't really matter.
