The test was sometimes timing out due to a race condition. In OS X, events for `fs.watch()` might only start showing up after a delay. This is a limitation of the operating system. To work around that, there was a timer in the test that delayed the writing of the file by 100ms. However, sometimes that was not enough, and so the event never fired, and the test timed out. Change the timer to an interval so that it fires repeatedly until it is picked up. This change only affects OS X. Fixes: nodejs#8511

@Trott, what about updating "watcherClosed" to use "let", and "interval" to use "const"? |
|
Linter passed, OS X passed, and Windows passed. The test does not run on any other platforms. So CI looks ✅ as far as relevant results go. |

Description of change
The test was sometimes timing out due to a race condition. In OS X,
events for
fs.watch()might only start showing up after a delay. Thisis a limitation of the operating system. To work around that, there was
a timer in the test that delayed the writing of the file by 100ms.
However, sometimes that was not enough, and so the event never fired,
and the test timed out.
Change the timer to an interval so that it fires repeatedly until it is
picked up. This change only affects OS X.
Fixes: #8511
