Microsoft decided a while back that the perfect time to install OS
updates was when a windows server or workstation was told to shut down.
Back in the rgmanager days, this was a problem because rgmanager
terminated a resource that didn't stop in two minutes. So while a
client's windows server VM was saying "Do not power off your computer!",
the cluster pulled the plug.
So we set an INFINITE (well, that needs to change now) so that if this
happened, the cluster would keep waiting. It's dumb, but it is what it is.
