John,
Thanks for the reply.
In this case, would the body of my function run in a separate thread
via forkProcess (that's what is needed, maybe I didn't make it clear)?
In my previous project, I had to do like this (probably not very
portable, at least requires System.Posix):

No; at least not automatically. The idea is that a function that is

Your best bet would be to start with these instances in HSH.Command:
instance ShellCommand (String, [String]) where

John all,
I use HSH in my project where several external programs and Haskell
functions need to be piped together: HSH is of great help here.
I however came across the situation when one of pipe-connected
