----------------------------------------------------------------

Since GTEST filter [does not 
support|https://github.com/google/googletest/blob/master/googletest/docs/advanced.md#running-a-subset-of-the-tests]
 boolean AND operator and does not support composition (to emulate AND operator 
using De Morgan's laws), we should either:
 1) Fix Mesos containerizer and Mesos tests to support launching ROOT tests in 
parallel
 2) when GTEST_FILTER is specified, run all tests in sequential mode

>             Project: Mesos
>          Issue Type: Bug
>            Reporter: Benjamin Bannier
>            Priority: Major
>              Labels: parallel-tests, test
>
> Users expect the be able to select tests to run via {{make check}} with a 
> {{GTEST_FILTER}} environment variable. The parallel test runner on the other 
> hand programmatically also injects filter expressions to select tests to 
> execute sequentially.
> This causes e.g., all {{*ROOT_*}} tests to be run in the sequential phase for 
> superusers, even if a {{GTEST_FILTER}} was set.
> It seems that need to handle set {{GTEST_FILTER}} environment variables more 
> carefully.
