In general, you're absolutely correct. But in this case, it still
sounds very likely: infinite recursion of a properly tail-recursive
function would loop rather than cause a stack overflow, which would
explain everything, except for why it's not actually an infinite loop;
I suspect the macOS code somewhere does modify things asynchronously.
