tracker-monitor-test sometimes fails
Seen here, for example: https://gitlab.gnome.org/GNOME/tracker/-/jobs/64762
I suspect that this is a timeout issue, as it is hard to reproduce locally.
If we just increase the timeout in the test then execution of tracker-monitor-test will become even slower than it is now. Perhaps instead we should make the timeout configurable via an environment variable, so that we can adapt the test for environments where IO is slow such as our GitLab CI runners.
