I think the easiest thing to do is:
from __future__ import with_statement
# This is to protect stdout and stderr.
output_lock = threading.Lock()
def printf(s, file=sys.stdout):
"""Print s to file and then flush it.
This function uses output_lock so that all writes to stdout and
stderr are synchronized.
Note, the caller is responsible for adding the newline.
I looked into using the logging module, but it turns out that the one
place I write to stdout is via the csv module:
Hence, I use printf instead of print, and I explicitly manage a lock
in the one place where I can't use printf.
