> In the following code snippets, the test tries to check the renewCount for the token
to verify if the FileSystem has been de-queued.
> {code}
>     @Override
>     public long renew(Configuration conf) {
>       if (renewCount == MAX_RENEWALS) {
>         Thread.currentThread().interrupt();
>       } else {
>         renewCount++;
>       }
>       return renewCount;
>     }
> testAddRemoveRenewAction() {
>   // some test code
>   assertTrue("Token not removed", (tfs.testToken.renewCount < MAX_RENEWALS));
> }
> {code}
> On slower machines, the renewCount can actually reach MAX_RENEWALS resulting in a test
failure.
> renewCount should not be used to verify this.
