Mmm. I'm not free of the code yet. After the release I got to thinking
about synchronous messaging across mailboxes, wrote some test code and
found a number of bugs--including some inherited from the AsyncFP
code. So work on presentations is delayed by a week. See
https://sourceforge.net/p/jactor/blog/
(It has been a long time since any real bugs have been uncovered, and
this is a first for the JActor project. Guess I was overdue.)
