[Tarantool-patches] [PATCH 0/2] Qsync flaky tests, next iteration

[Vladislav Shpilevoy]

The tests keep failing, each time in a new way. The patchset
attempts to fix them again. Worth mentioning, that I couldn't
reproduce the fails in the issues, and the fixes are based on my
assumptions + on the passed CI (failed, but in other tests).

How 5168 managed to happen I can't even imagine, but the flaky
test case is reworked in this patchset anyway, it was incorrect.

I suspect these fails depend on disk speed somehow, not on CPU.
Especially looking at how 5167 failed. On my machine
reproducibility seems to be so low, that I couldn't get it, even
with tens of workers.
