Ah yes, I have also issues with the Windows fault handler (the popup). I disabled this popup manually in my Windows XP box.

Instead of skipping the test, I prefer to disable temporary the popup by setting the right registry key (and then restore the previous value or delete the key).

faulthandler causes fatal errors, but test_capi does also test a crash (I don't know which test exactly). I always have to click on the popup to continue to execute the test suite :-(
