Sure, if you want to pay the CPU and memory overhead of allocating a 4GB buffer :-) > Should communicate() be "fair" between stdout and stderr?

Windows isn't concerned by this, since it doesn't use a selector, but threads. For the other OSes, that's why I opened this issue (you forgot AIX in your list :-). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19929> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
