We can certainly do something like that - the progress handler sees all output 
even if it doesn't contain anything interesting to it (e.g. % complete). The 
trouble comes when the process prints out nothing - such as when linking a 
very large binary. I'm not sure how you would introspect into that part of the 
process.
