Description of problem:
During testing of:
https://bugzilla.redhat.com/show_bug.cgi?id=2080227#c9

everything seemed to be ok. However, some time passed and it look like there is another fd leak on horizon.


Version-Release number of selected component (if applicable):
rhel8 and rhel9 packages seems to be affected.
tuned-2.20.0-1.el8.noarch and same for rhel9.

How reproducible:
Use test.

Steps to Reproduce:
1. use test
2. look at results
3. decide if pass/fail?

Actual results:
