> Steps to repro:
> 1) Run a long running query.
> 2) Kill one of the non foreman drillbits.
> 3) Start the killed drillbit immediately. 
> Sporadically the running query hangs on both server and client. I suspect this has to do with the fact that the kill and start was so quick that the drillbit was never detected as failed. 
> The fix would involve keeping some relevant information of the running drillbit(maybe pid) and checking if its the same drillbit which is working and not a new fresh drillbit.
