🐛 Fix possible leak (W.i.P.)

[cupakob]

Not closing os.File must not, but may lead to a leak. It is better to close it manually instead of waiting for the next GC to be triggered

Hi @cupakob. Thanks for your PR.

I'm waiting for a kcp-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi @cupakob, I'm not sure this is a flaky test. Have you verified that the same test works for you locally?

@embik currently i don't have any changes in the branch (all changes are commented), but the tests are still failing...it looks like flaky tests somehow, right?

I think you're right, the test occasionally flakes. You can see in older runs that it used to fail sometimes before this PR. Apologies for the confusion caused by it.

I think the consistent failures we saw earlier in this PR had a differentiation though: They ran into the 2h timeout, so those jobs were running for much longer. The flakes are usually happening within the first 15-20 minutes.

all good, not a problem at all ;)

okay, but I don't have an explination, how the defer function, where I close the file, can cause a 2h timeout...any hints are welcome.
