Turns out the default for hugepages setup is making it inaccessible.
Using new --user flag fixed that.

Probably should add that to docs about running tests.


With 1G of hugepages:

Ok:                 96  
Expected Fail:      0   
Fail:               1   
Unexpected Pass:    0   
Skipped:            5   
Timeout:            0
