I didn't say "deplete /dev/urandom", I said that when reading from /dev/urandom "you're depleting your entropy pool". So reading from /dev/urandom won't block, but it can starve processes that read from /dev/random, and that's a problem. See https://groups.google.com/forum/#!msg/fa.linux.kernel/Ocl01d8TzT0/KDCon2ZUm1AJ I think since 2.6 Linux uses two different entropy pools for /dev/random and /dev/urandom, but that might not be true for every OS. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21305> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
