92d9778dd7 fix race on primary switchover 
solution: wait until all in /mars/resouce-*/ has stabilized
for 60s and all known logfiles have been migrated.
This more a workaround than a solution and should be fixed
in MARS FULL.

81bfb9471a fix network race on primary/secondary switch 
The race could lead to unnecessary split brain.
Now we wait until everything in the resource directory became stable
for at least 60 seconds. This may be somewhat too conservative
when having k>2 participants on the same resource.
