> As described in [1], each Ignite node has a number of system-critical threads. We should implement a periodic check that calls failure handler when one of the following conditions has been detected:
> # Critical thread is not alive anymore.
> # Critical thread 'hangs' for a long time, e.g. while executing a task extracted from task queue. 
> Actual list of system-critical threads can be found at [1].
