Using the API to tell if a compact has been done

[Wayne Conrad]

I've subscribed again, from another email address, because the list 
decided that my first subscribtion was a eeeeevil spammer.  I hope 
that's OK.  Anyhow...

I've written a cron job that periodically compacts all databases on all 
servers, but it needs an automated test, and an automated test needs a 
way to know that compaction happend (or, at least, was triggered).  
Other than seeing the file size change, is there anything I can do from 
the API that will show that my cron job caused compaction to happen?

I'm running 0.11.1.  I can upgrade to a later version if it will make 
things easier.

Thanks,
Wayne Conrad
