If I'm understanding the test correctly, the part of the test that is flaky is actually invalid. It checks to see if the function passed to setTimeout() executes in the same second as call to spawnSync() finishes. This will not always necessarily be the case, and the test will only get flakier if more things are added to it. (There are two other test cases below the flaky one.)

There's already an assertion to confirm that the spawnSync() ends before setTimeout() runs, so I'll submit a PR to remove the check altogether rather than do something like convert the timestamps to nanoseconds since start and make sure the one set by setTimeout() is greater than the one set by spawnSync().

test: make spawnSync() test robust
afbda2c 
The test had checked that a timer fired within a period after
spawnSync() returns. The result was a test that sometimes was
flaky.

Because there's no guarantee of how long a timer will take
before running, remove the check. There is a check that the
timer runs after spawnSync() so that is sufficient.

Fixes: nodejs#2470
