Ryabov Dmitrii commented on IGNITE-10437:
-----------------------------------------
[~ilantukh], I suppose because of delay, threads worked separately, one by one.
With high delay there was more often situations when overflow doesn't happened.
With lower delay overflow happened is more often, but test still was flaky. So,
I removed delay to be sure that overflow is happened.
> GridCacheWriteBehindStoreMultithreadedSelfTest.testFlushFromTheSameThreadWithCoalescing
> is flaky
