Hmm. Does this trick work only on U*X?
import sys, os, time
def tryit():
print "part 1",
time.sleep(3)
print "part 2"
print "On the console, this should sleep before displaying both parts..."
tryit()
# Reattach sys.stdout to an unbuffered file object.
newout = os.fdopen(sys.stdout.fileno(), 'w', 0)
sys.stdout = newout
print "This time the first part should before the pause."
tryit()
