The gambit manual section 17.7.2 explains how to redirect stdout/stderr of child processes opened via `open-process` and siblings to the newly created port.

That's the closest I could find to what I want to do:

Run the child process and process return process the output when the child exits normally and raise an exception (containing what the child wrote to stderr) otherwise.

I don't mind a few tricks. The fewer the better. But I need this on Linux and Windows, at least that it.

But I don't see how to do that with Gambit.

Thanks for any hint.
