[Chicago] capturing output from subprocesses

Hi Ian,

I could try that, but in the case of the real application whose output I 
want to capture, I have no control over how much output it produces.

Do you have any thoughts about recapturing the output of an aborted child 
process before the memory that is buffering its output gets blown away?

with thanks,

Noel Taylor
