Log message:
	- When a cluster log resumes, the server must re-read the log device.
	However, it doesn't _need_ to happen until a request comes in which
	forces an election.
	
	If a resume/suspend loop is tight enough, it is possible for a
	log read to happen after the log device has been suspended.
	
	The fix is to force the log read during the resume call.

Log message:
	Bug 214487: "Attempt to mark a already marked region" messages when ...
	
	Similar to the last checkin.  When a log server moved, all entries in
	the clear region list were removed rather than just those that where
	associated with the log that moved.  Again, this would cause the server
	to report that the regions where already marked when the next mark
	request would come in.
	
	I believe that this action was harmless (but annoying).

Log message:
	Bug 214487: "Attempt to mark a already marked region" messages when ...
	
	When a log server moves (like durring a failure or the mirror being
	shutdown on that node), the clients send the new server the regions
	that they have marked.
	
	However, the clients where sending _all_ of the regions they had
	marked for every mirror that was active - even for the ones whose
	log server had not moved.  This was causing those servers to report
	that they already had those regions marked.
	
	Other than the annoying messages, I don't believe there were any
	side affects of this bug.

Log message:
	Bug 217438: scrolling kernel requests to mark mirror regions
	
	It is sometimes possible for a mark request to be issued on a region
	that is being recovered.  The mark must be delayed until the recovery
	is complete.  This is what was happening, but a rather severe error
	was being reported and the (mark region) retries were happening too
	fast.

Log message:
	Bug 214517: hung cmirror operations due to looping mirror region requests
	
	Once we've completed handling a new server, we must reset the 'new_server'
	variable, so that if we need to retry a request we don't go through the
	whole process again.
	
	Also, added more error reporting for when a request must be retried.
