test_xcb tests are considered too unstable
While packaging this packaging for openSUSE, we have repeated problems with stability of tests, particularly tests in the module test_xcb.
See build log pro erorr messages, and list of all packages used.
Related to this issue: test_xcb_window sometimes crashes on Python 3.10 64 bit (the failure wasn't observed on 32 bit neither on older pythons):

... now it crashed on Python 3.9. It is just unstable.
We already tried to fix this problem in https://github.com/Kozea/cairocffi/issues/85, but it looks like it’s back.
We sometimes have the problem on GitHub Actions, but only on Windows. If it fails elsewhere, then it’s probably a problem in our code. If someone is motivated to use a debugger to see where the problem comes from, it would be very useful.
@MeggyCal is my colleague at SUSE, so obviously this has nothing to do with Windows.

Yes, I’ve seen the tracebacks, and that’s really sad because I didn’t see this problem happen on Linux since #85 😢️.
