shell vs. process

In Revolution, which function is better for calling a long-running
external process and reading data from the process in a non-blocking
format, for instance, streaming the output from tcpdump into a text
display?

Looking at the docs, it appears that "process" is what I want, but I saw
something that says that "open process" on OS X is only useful for
launching applications...not launching background command-line processes
and reading their output to stdout as one would expect to do on a
Unix-style platform. Since I am targeting OS X, I need to know how
others handle this.
