Amaury proposed in the issue (#11633) that print does flush if the end
option is used. I vote +0, but only if we do that for the default file
(sys.stdout).

I only vote +0 because I think that it is easy to modify the code to add
a explicit call to sys.stdout.flush(). Sorry, but programming is hard:
you have to learn things! A better idea would be to *document* that
print() may not display immediatly the message if it doesn't contain a
newline (eg. if end=''), and give the solution (sys.stdout.flush()).
