Random and short lived index inconsistent errors #11
Description
Creating issue here, as I feel it may be specific to the experimental fork. Seeing queries fail with runtime error index inconsistent remarks; for example:

Initially I though this pointed toward db corruption and I rebuilt a second instance https://overpass02.opengeofiction.net/ however I see the same issues there. Also, they are random and short lived - a query will complete fine and the same query will occasionally have the issue and then come good again. I ran some tests overnight - just two different queries, repeated every second. Out of 68944 total queries, this issue happened 89 times. I've zipped up those responses, and the test scripts - attached. I added a bit of extra output to the error message, the patch to file_blocks.h is in the zip too.
