Many thanks for the patch. I'm just not sure about the default
escalate time. You set it to 30 seconds, perhaps it should be set
to something longer. Otherwise some cluster configurations where
the stop operation takes longer may have problems. I have no idea
which value should we use, but I would tend to make it longer rather
than shorter.

Cheers,

Dejan
