Seems to be working. Improved a bit: only close/open when doing a straight viewport listing and do a close/open when doing an initial list of mailboxes. Closing ticket - there may be other places this is useful, but that needs to be determined on a case-by-case basis.

Added a test use case for message listing in dimp. Will observe for unwanted side-effects, etc.

To avoid blocking operations in other tabs/browser windows, or in DIMP's case, simply other ajax requests, we should close the session (session_write_close) whenever possible before a long running operation. We do this some places, but haven't done it in others because of the need to update the session later. Turns out you can re-open the session by calling session_start (we'll probably need Horde::setupSessionHandler) again, as long as headers haven't been sent. Especially with DIMP I think this would be useful to try. The thing I noticed locking on earlier that brought it to mind was emptying a large mailbox; DIMP generating a message list might be another. I'm sure there are more.
