[noname0443]

It is annoying to wait for tests which are going to fail :(

It works:

• https://github.com/yandex/mysync/actions/runs/18500068887
• https://github.com/yandex/mysync/actions/runs/18500068834
• https://github.com/yandex/mysync/actions/runs/18500068871

For some reason, tasks that are already running cannot be canceled :\

Supposedly, we have to specify hard timeouts

jobs:
  test:
    timeout-minutes: 90

In the previous comment, it might be an error of a representation - the jobs under the hood don't run.

Let's cancel the tasks and check again their number.

I see the same result:

• https://github.com/yandex/mysync/actions/runs/18554375293
• https://github.com/yandex/mysync/actions/runs/18554375303
• https://github.com/yandex/mysync/actions/runs/18554375306

And there are 20 "in progress" tasks:

At least, "leaked" jobs do not affect us.
