I'm not sure why the CI is failing randomly. I have increased the timeout from 2 seconds to 5 seconds. (Everything works fine on my local Ubuntu 22.10)

I have increased the timeout from 5 seconds to 10 seconds, and the failing tests are not related to this PR.

I checked the GNU test logs and found that this should also fix #4073, which is caused by the split subprocess (`filter`) not being killed by the `timeout`.
