Are gtests executed on the primordial thread?

Hi all,

It seems to me the gtestLauncher executes its tests on the primordial
thread. Is that correct?

If yes, would it not be better to run the test on a separate thread,
similar to how the standard launcher creates the VM? That way the tests
would be closer to what the actual usage scenario of the VM.

Depending on the platform, there are quite a bit of differences between
running on the primordial thread or on a secondary pthread. Currently
invoking the VM on AIX on the primordial thread does not work at all - we
excluded that scenario for a number of reasons when doing the initial port,
and even though we could rethink this decision I would prefer not having to
deal with that right now just to be able to run the gtests.

Thanks, Thomas
