B-C: threads + DEBUGGING global destruction

[ribasushi]

Something as simple as this failed tests like this.

Is this expected?

Failed 2 tests out of 2435, 99.92% okay.

Looks like I have to skip those tests for these, esp. under global destruction tests.
And we need to slowdown the travis testsuite by ~30min by re-adding thr+debugging again.
