   I have seen #282 and I'll definitely vote for it :) 
   
   Can you confirm the following about the logs above
   - you were using the patch from #280 in a live system
   - you still observed the concurrency issue with the patch applied 
   
   And expand on this from #282
   > Attempts to make it thread safe like [2] [...] ultimately did not manage to protect 'optimized' raw access to the underlying data thus not fully addressing the concurrency issues.
   
   Do you know what the 'optimized' raw access you speak of is and where and when it used to occur ? I'm curious because dispose would set the ref to underlying to null but if the 'optimized' access already had the reference it shouldn't have failed...
