Bug Description

Failed test cases : hugemmap01 hugemmap02 hugemmap04 hugemmap05 hugemmap05_1 hugemmap05_2 hugemmap05_3 hugemmap06 hugeshmat01 hugeshmat02 hugeshmat03 hugeshmat04 hugeshmat05 hugeshmctl01 hugeshmctl02 hugeshmctl03 hugeshmdt01 hugeshmget01 hugeshmget02 hugeshmget03 hugeshmget05

However, if you run this test suite directly, all these test will pass.
So I think this is caused by some other failures before the hugetlbfs test.
