Shouldn't the test should skip if it fails to determine if it can mlock or not?
A while ago I had put together this: http://paste.debian.net/1008934/ to fix
the test.

It is interesting that when I run the tests with "--r mlocked*" the first
subtest is executed fine and passes but all the successive subtests skip. If I
run them individually they seem to run fine most of the times. Are we leaking
something?
