That's a good question. O'Reilly's "Managing IMAP" gives instructions to 
shut down Cyrus before running reconstruct, but doesn't explain why. 
That book is pretty old, however. There's nothing in the reconstruct man 
page about it, either.

Maybe the reconstruct command doesn't protect against the delivery of 
new mail while it's running, possibly resulting in more corruption? 
Also, will reconstruct interfere with idled in any way?
