> The stout test \{{FsTest.Used}} is flaky,
> {code}
> [ RUN ] FsTest.Used
> ../3rdparty/stout/tests/os/filesystem_tests.cpp:817: Failure
>  Expected: used.get() / b.f_frsize
>  Which is: 1246447B
> To be equal to: b.f_blocks - b.f_bfree
>  Which is: 1246384
> [ FAILED ] FsTest.Used (0 ms)
> {code}
> Looking at the test implementation this appears to be due to the test acquiring the two compared values non-atomically,
> {code}
> TEST_F(FsTest, Used)
> {
>  Try<Bytes> used = fs::used(".");
>  ASSERT_SOME(used);
> struct statvfs b;

>  EXPECT_EQ(used.get() / b.f_frsize, b.f_blocks - b.f_bfree);
