Actually, it's in version 0.4.4 already. Only runall.sh is executed,
since it executes that other tests. I'm adding test_uatomic too for the
next release. Note that this is a really braindead uatomic ops test, as
it only checks for single-thread consistency of the operations. We
should really extend this test to multithread someday.
Thanks,
Mathieu
