I'm not that familiar with ACE, so I can't really comment.
These days, I prefer programming in Java over C++, I see Java as a
"better C++". I don't miss seg faults and other cryptic messages
that are experienced with C++. C++ has its place, but I usually
choose Java over C++.
Implementing Ptolemy II in Java gave us an opportunity to do a
redesign from the ground up. For example, Ptolemy II handles
mutations of the model connections on the fly. Ptolemy Classic could
have been modified to do that, but it would have required quite a bit
of work.
We can run Ptolemy II models in security sandboxes, which would be
difficult, if not impossible to do with Ptolemy Classic.
Ptolemy Classic did use pthreads, but supporting different versions of
the various C++ compilers was a real time sink.

In your opinion do you think ACE (Adaptive Communication Environment) http:
//www.cs.wustl.edu/~schmidt/ACE.html tackles the threading under C++ much be
tter since ACE makes programming in a multi-threaded environment much simple
r? Had ACE been available for Ptolemy Classic, would it have prevailed?
What if SystemC-2.0.1 was to use ACE instead of QuickThreads and fibers? Be
tter alternative?
Thanks for your links and input,
