The shortcut support gives you a fast path _around_ the POA, not
through it.

For the vast majority of purposes, the normal colocation support,
which goes through the POA, is fast enough. You don't need to do
anything special to get that. It just automatically happens if the
object is in the same process as the caller. It is not worth the race
condition risks of using the shortcut unless profiling tells you it's
really necessary.

Cheers,

Duncan.
