Is there something new about how/when this test is run during continuous 
integration?  The test time is dependent on the value of RTE_MAX_LCORE 
which is currently 1536.  When I run the test locally it takes around 50 
seconds to complete and completes without errors.  If I reduce the value 
down to 128 the test completes in around 5 seconds.  The current value 
has been in the code for nearly 2 years so I'm curious why the sudden 
change in CI results.

We could could reduce the default value for RTE_MAX_LCORE (I don't often 
have access to a system that actually has this many cores) or we could 
skip the test in this situation as well.
