I would like to revert it if only simplify the code, but I don’t feel
that strongly. It may have been fixed in later releases of 10.10. It
would be nice if someone using 10.10 could check, but I don’t know who
could do that.

It might be worth putting a comment or two in to explain why it’s
using this asynchronous method.
