Various tests failures on i686

The errors seem intermittent, sometimes the tests are successful. This make it difficult to reproduce.

Run the tests as cargo test -- --test-threads=1, that might workaround the problem.

I will extend the API to reuse a pool and have the tests use the global pool to avoid this.

Does this happen when building locally or only on Fedora CI?

I can't test locally I don't have access to a i686 system.

Run the tests as cargo test -- --test-threads=1, that might workaround the problem.

I will extend the API to reuse a pool and have the tests use the global pool to avoid this.

I will try this.

I'm getting similar thread panicked error messages for prep_8tap tests on Arch Linux x86_64 after the introduction of these tests by recent commits 8fa818b and cd2aadf. Like this:

---- asm::x86::mc::test::test_rav1e_prep_8tap_regular_smooth_bd_8_avx2 stdout ----
thread 'asm::x86::mc::test::test_rav1e_prep_8tap_regular_smooth_bd_8_avx2' panicked at 'assertion failed: `(left == right)`

Adding -- --test-threads=1 does not solve the issue. The put_8tap tests are passing.

The original issue is for i686, but is this releated in some way?
