test_multiprocessing_spawn.test_manager: test_async_timeout() failed on Windows (x64)

[vstinner]

When the test failed in 2013, 10 years ago, the fix was to increase the timeout from 200 ms to 1 sec: issue #63798.

Windows (x64):

0:14:39 load avg: 13.67 [336/469/1] test.test_multiprocessing_spawn.test_manager failed (1 failure) (2 min 26 sec) -- running (1): test.test_multiprocessing_spawn.test_processes (2 min 36 sec)

It made tests 1.5 minutes longer. See #111284.
