We could summarize our finding so far about the Julia console output
~ For Windows, with the latest nightly 0.3.0 Julia version

- Warnings are written to STDERR, they can easily be redirected, captured 
to a variable
- Error messages might or might not get written to STDERR, but they cannot 
be captured to a variable, because the code execution aborts beforehand 
[bad]
-- I also failed to get error messages via another thread redirecting STDERR
- The output of print() is written to STDOUT, which can be redirected and 
captured. This does not seem to matter, because we can directly print to a 
pipe
- The console output is not written to STDOUT as if it were printed: it 
cannot be captured to a variable [bad]

Could someone verify these? Especially the last bullet point looks suspect.

I'd like to find workarounds for error messages and regular console output. 
We can then log them in files, or pass them to other applications via the 
clipboard.
