I'm far from being the expert here to work on improving them, hence my
suggestion to tune-down the execution time my first approach. The
consensus is to have some sort of work-around in some acceptable
time-frame. Improving, on different platforms, is an endeavour on
itself.

Have another suggestion, similar to Nightly runs. Have an extended
namespace for GEM test that take/require a longer runtime and run them
before Nightly kicks in. Basically have a shorter run-time for BAT and
longer runtime (under that extended name) for extended runs.  Atm, I'm
timing concurrent_blit on a couple of platforms to see how much time it
normally takes. If under a couple of hours that would be acceptable.
Hoping that by segregating GEM tests would remove the noise
I'm seeing for Nightly runs.
