Well, as Yvan showed with his recent patches, we seem to be using
DejaGnu in an unusual configuration, which uncovers corner case bugs.

I'm seeing "random" results in sanitizers tests, which is a relatively
recent addition to GCC.
And I know we are not the only ones having trouble with the
sanitizers results.

I would just like to add determinism, to remove one cause of randomness.
