IIRC, the default handler is apartment-threaded only, meaning that a
default handler object cannot be used on a thread other than the one
it was created on. Adding constructs like this introduce confusion to
future developers about whether the code is or isn't thread-safe and
so it should be avoided and a non-thread-safe construct used instead.
