This test failed on the commit that introduced the test (https://github.com/facebook/buck/commit/5a79d2aeb14c87c1de8b8d17aee8f90009cfe76d) but passed on a subsequent commit (https://ci.appveyor.com/project/Facebook/buck/build/3554). It appears waiting for 3 seconds is not enough on AppVeyor (maybe due to noisy neighbors?), so let's double it.
