Steps:

• rename src/vs/platform/files/test/node/recursiveWatcher.integrationTest.ts to src/vs/platform/files/test/node/recursiveWatcher.test.ts
• find the subsequent watch updates watchers test and for convenience change it to test.only
• comment out the return await timeout(5); in that test file
• scripts/test.sh (it may require a couple of attempts)
