In my case, the corporate box I am using has a cron job pruning old
files in /tmp, where I have to use for my revlib.
I really don't think "intrusion detection" or "forensic clue" should be
the concern here. inode signatures are very weak in term of security
measures; if people can mess with your revlib you are doomed anyway.
Printing a warning message is reasonable though.
Regarding the atomic operation concerns, are you sure tla currently
support concurrent access to the revlib?
