Charles-François Natali added the comment: Of course, when I have 300 connections to remote nodes, I use poll() to multiplex between them.
But there are times when you can have a large number of threads running concurrently, and if many of them call e.g. subprocess.check_output() at the same time (which does call subprocess.communicate() behind the scene, and thus calls select/poll), then one extra FD per instance could be an issue. For example, in http://bugs.python.org/issue18756, os.urandom() would start failing when multiple threads called it at the same time. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19465> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
