It's a large conversion with a lot of moving parts and about 1100
callsites. I've tried to minimize conflicts, but without being able to
carry everything in a single tree, it's made things extremely complex.
I'm doing my best to avoid these glitches, but I haven't been 100%
successful. This is mainly the fault of the conversion uncovering more
and more corner cases as I went. :(
