I saw one new test_ignore() failure on Travis CI in my 3.6 PR, whereas 3.6 already uses PIPE_MAX_SIZE for test_ignore(). https://github.com/python/cpython/pull/7315/ https://travis-ci.org/python/cpython/jobs/386637729 Hum, test_ignore() uses PIPE_MAX_SIZE, whereas the test fails on Linux where we use a pair of sockets, no pipes. Maybe we should use SOCK_MAX_SIZE? Notes on pipe size: * /proc/sys/fs/pipe-max-size * bpo-17835: add support.PIPE_MAX_SIZE (4 MiB +1 B) * bpo-18643: add support.SOCK_MAX_SIZE (16 MiB)
