I do this alot in my current project and I have a small little framework around this because IIRC the "problem" is that your call to #output will block until #atEnd. So what you want to do if you do not want to block is to fork off a background process that reads without blocking. This works really well for me, so I run multiple of these in parallell and each is given its own background Process that reads and copies into a WriteStream on a String. So if I ask my "wrapper" for the output it will ask this stream for its contents instead. regards, Göran
