File vdsm/virt/vm.py:

PS2, Line 920: mergeCandidates
how do you use this?


PS2, Line 936:         if not self.conf['_blockJobs'].values():
             :             return {}
why not just:

  if not self.conf['_blockJobs']:
    return {}

plus, more important: let's check carefully about the locking here.


PS2, Line 941: stats_cache
please note that this is updated each 15s - and it is modifiable by the users. 
Is this good enough for live merge?


PS2, Line 981: getVolumeInfo
how costly is this?
