The critical thing that is needed from the shell to allow -jN to work is
that it can be invoked with open file descriptors (a pipe in this case)
and that it can further pass those open file descriptors to programs it
invokes, unmolested.

As far as I know that's all you need from the shell to get -jN working.
I don't know what this means in the context of any temporary batch file
creation or other special things that happen on Windows systems.
