Unfortunately Benno, your (and my) intuition is wrong, as shown by the
testing that Abramo and Steve did about 3 weeks ago. In the extreme
cases, a requirement for in-process is the right thing to do.

However, we need to support out-of-process too since it will work even
for <3msec latencies in almost every case. Thats why the audioengine
API I am in the midst of proposing is independent of whether or not
the "client/plugin" is in-process or out-of-process, though I have to
admit to a bias toward out-of-process right now, since it solves many
problems without introducing many new ones.
