When running a very large query on a cluster with limited resource, we noticed that one of the node's VM thread freezes the fragment threads as it tries to do some work (GC perhaps?). This is a clear indication that the query is stuck in a weird state where it might not recover from.
Under such circumstances, it makes sense to cancel or atleast warn the user on that page of the query exceeding a certain threshold. 
For detecting this, the user will find that the {{Last Progress}} column in the Fragments Overview section will show large times.
