> Memory leaks on restart Ignite node with enabled persistence at ThreadLocal.
> The ThreadLocal {{DelayedPageReplacementTracker#delayedPageWriteThreadLoc}}
> looks suspicious.
> I've added the simple test to memory leak on restart Ignite nodes from the
> thread that is not terminated after node stopped.
> This case is very useful e.g. for all jUnit cache tests that starts Ignite
> cluster from the {{beforeTestsStarted()}} (this method is called from the
> {{main}} thread and alive for all tests in a test suite).
