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.

I jumped straight in and tried to hack without learning some Smalltalk
basics but after spending a day with Pharo By Example I am beginning to
make some progress.
Is the Transcript in Pharo 1.4 different from the one used in the PBE
image? It displays ThreadedTranscript when I check its properties and it
doesn't seem to hang like the PBE image.
Some example code would really help here.
Thanks
Transcript was replaced at some point - I "think" it was after PBE
publication. I link to some related posts below.
Regarding sample code... what are you trying to do? The way I commonly
use the Transcript is...
Transcript crShow: something asString, '---', somethingElse asString.
asString might not be the most efficient way, but its simple. Without
'asString', using the comma to concatenate strings often does does not
work since non-string classes generally don't understand comma.
