Hi Robert, If you are doing this in a publicly-released package, I would suggest to make very clear to your users that this is happening and either provide a way to disable redirection, or send the captured output to a log instead.
The functionality is available via `redirect_output`: http://julia.readthedocs.org/en/latest/stdlib/base/#Base.redirect_stdout A minimal example: ``` realout = STDOUT # grab the old output stream (rd,wr) = redirect_stdout() # get redirect handles @async while true readline(rd) # effectively /dev/null end println("Hello into the vacuum") # should not be displayed println(realout, "My output") # you need to specifically write to the old stream handle to get visible output ``` (I thought that perhaps the reader task might be unnecessary, but in a quick test - on Windows - it seems that overflowing the buffer will deadlock the process).
