Hi Karen, et al.
I've been looking at this in a bit more detail, and I'm still not convinced
that using the multiprocessing module in the Engine is the correct approach to
this - sorry - but I'll explain why...
I think Karen and I both agree that there's no need to convert to
multiprocessing now; the purpose of the investigation was to determine
if there were any barriers to converting in the future, should a
valuable use case present itself, and if such barriers exist and it's
significantly easier to remove them now than it would be later, to
consider the risk vs. reward of doing so.
Based on her investigation and your response, I don't think there's any
barriers that can't be overcome later just as easy as they could now; so
there's no apparent benefit to overcoming them now. (That includes the
alternate proposal of running 2 checkpoints simultaneously in threads,
and having the threads spawn full subprocesses to overcome the
limitations of the Python threading module)
