   @dbw9580 
   What would happen in the following scenario.  Let's say you have user A who 
executes a query using IPFS and which spins up new Drillbits.  User B then 
decides to execute a query that does not use IPFS.  Is it possible that if 
these two queries are concurrent, could user B's query end up on the Drillbits 
for IPFS and then either not find data or cause some other problem?
   
   Alternatively, what would happen if user B executes a query while user A's 
IPFS queries are running.  What would happen if user A's query completes before 
user B?  Would it tear down the Drillbits and cause a crash?
   
   I'm asking because I really don't know here..
