[Cook] Predefined variable [arg]

[Jody Hagins]

In the User Guide, there is a caution concerning this variable, w.r.t.
parallel execution.  I must be missing something, because it seems to
make calling anything but the most trivial functions useless in parallel
mode.

Can someone please elaborate on the definition in the User Guide?

In addition, I do not seem to understand when multiple threads will be
used.  I assume that a single thread of execution will be used to build
the entire graph, then multiple threads of execution will be used to run
the recipe bodies, if possible.  What does this mean for late binding
ingredients, and other uses of parallelism?


Again, thank you very much!
