[#serial] not respected with tokio::test?

[schulte-lukas]

Is it possible that [#serial] is not respected when using Tokio? I have a test definition as below (many in fact, which should be run one at-a-time). Each test is resource intensive and should be run in serial. But, all tests are run simultaneously - machine runs out of memory and kills the process. When running each test individually via command-line, everything stays in limits and all tests pass.

OS: ubuntu 20.04

#[tokio::test(flavor = "multi_thread")]
#[serial(slt)]
async fn some_test_of_mine() -> CliResult<()> {
    ...
}

#[tokio::test(flavor = "multi_thread")]
#[serial(slt)]
async fn another_test_of_mine() -> CliResult<()> {
    ...
}

...

Solved a different way...

Finally got to this one. So, there shouldn't be anything odd there. If it was running multi-process maybe, but multi-thread should just be fine. #122 adds explicit testing to this just in case, but I'm not able to reproduce the problem.
