 Thanks for the report. Using a depth counter like this seems like a sorta
 hackish workaround that has the potential to cause problems with
 legitimately complex dependencies. How about doing some actual loop
 detection? Like maybe `recurse_deps()` should accept a third param that is
 a flat array of unique handles identified in the tree, and then if it
 detects that you're looking at a handle that's already been recursed, it
 will bail?
