On buildbot x86-64 Sierra 3.6, since build 163, test_read_pty_output() of test_asyncio started to hang:

Difference between pythoninfo of build 162 and 163:

-os.login: buildbot
+os.login: _timed

-os.uname: posix.uname_result(sysname='Darwin', nodename='mattb-mbp2.local', release='17.2.0', version='Darwin Kernel Version 17.2.0: Fri Sep 29 18:27:05 PDT 2017; root:xnu-4570.20.62~3/RELEASE_X86_64', machine='x86_64')
+os.uname: posix.uname_result(sysname='Darwin', nodename='mattb-mbp2.local', release='17.3.0', version='Darwin Kernel Version 17.3.0: Thu Nov  9 18:09:22 PST 2017; root:xnu-4570.31.3~1/RELEASE_X86_64', machine='x86_64')

-platform.platform: Darwin-17.2.0-x86_64-i386-64bit
+platform.platform: Darwin-17.3.0-x86_64-i386-64bit

-sys.version: 3.6.4+ (heads/3.6:aea95c2fbd, Jan  2 2018, 00:22:06)  [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)]
+sys.version: 3.6.4+ (heads/3.6:a70d5ff992, Jan  4 2018, 01:35:13)  [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)]

-sysconfig[HOST_GNU_TYPE]: x86_64-apple-darwin17.2.0
+sysconfig[HOST_GNU_TYPE]: x86_64-apple-darwin17.3.0

The os.login change is interesting and curious, and it also looks like a macOS upgrade from Darwin 17.2.0 to 17.3.0.
