1) What is the best way to determine if calibre is running?

2) Is there a way to determine if calibre is busy?

3) What happens if calibre is shutdown (using the --shutdown-running-calibre command line) whilst calibre is busy?

The questions arose from something that happened recently. I have a custom column to determine the type of book (e.g. eBook, Audiobook, Paperback) and when I added a new book and set the type I must have accidentality entered the value with a slightly different case (ebook instead of eBook). That seems to trigger a background update where calibre updated the opf of all my existing ebooks (over 5000 in number) and this process seems to have taken at least three hours.

So, if I want to shutdown calibre before running a backup routine, what would happen if I tried this whilst it was in the middle of updating all these opf files?
