In Python when the output of a script is going to a pipe stdout is
buffered. When sending output to tee that is very inconvenient.
We can set PYTHONUNBUFFERED, but then stdout is always unbuffered.
On Linux we can do:
PYTHONUNBUFFERED=T script.py | tee script.log
Now the output is only unbuffered for the current run and buffered for
other runs where the output goes to a pipe.
