I'm taking the risk of conflating several different
issues into one.  On the other hand, this might be a
useful synthesis to help us bottom out on "fork
problems" so that we can turn a snapshot into a stable
release[1]?

I've been trying to figure out strace incantations.
Hopefully someone more wizardly can help?  Is strace
the best/only attack vector on this?

I wonder if some strace like [6] would help?

Perhaps someone could suggest a helpful "cheatsheet"
of
what we might want to focus on in strace output of
these processes?

If it would be helpful to run strace against the
processes in the weather.sh fork example[7]
, or in the nonsense testcase example[8]
...what should the command line be, and what would we
be looking for in output?

Torfinn, any luck on SharedSection parameter tweaking
per the MS KB?
