If snapshot restoration fails with a UnlinkedAncientBlockChain (and you see Encountered error during snapshot restoration: Snapshot error Unlinked ancient blocks chain in the console) the client is stuck and Ctrl+c is not enough to shut down properly.

The error can be returned only from two places in this method.

Shutting down prints the expected Finishing work, please wait... (from here) but the unclean exit handling code in wait_for_drop() does not run. This is an indication that we have a deadlock when in this state.
