------------------------------------------------------------

Are the options

* remove_old_coords_on_view_change
* remove_all_files_on_view_change

save, so that e.g. if a server crashes and restarts only its own old files are removed?

> When we terminate a member (EC2's "terminate" function) or kill -9 it, then the file (or bucket data in S3) won't get removed. This leads to stale data. On EC2, I expect that virtualized instances are often simply terminated, so this problem is compounded there.
> SOLUTION:
> - Periodically write own data to the file system (FILE_PING) or S3 (S3_PING)
> - On a view change: remove all data that's not in the current view
