Eric Pouech : kernel32/tests: Filter spurious thread creation debug events.
Module: wine Branch: master Commit: 8aeca16ca552dd61b6efd1dc66c995f29dfe66b0 URL: https://gitlab.winehq.org/wine/wine/-/commit/8aeca16ca552dd61b6efd1dc66c995f... Author: Eric Pouech <eric.pouech(a)gmail.com> Date: Wed Jan 18 16:24:01 2023 +0100 kernel32/tests: Filter spurious thread creation debug events. On windows, we get some test failures as un-expected thread create debug events are sent. Try to filter them out in a couple of places.
