Thanks for the feedback.  Dejan, I have some SLES nodes that are running
around 30 pretty heavy VMs and I found that while I never go to 5s that
the time it would take to reboot was not a constant.   I have a feeling
that this bug in xen-list may take a while to be fixed upstream and
trickle down into the released xen packages so we may be using this fix
for a while.

The full longdesc now reads:

<longdesc lang="en">
When the guest is rebooting, there is a short interval where the guest
completely disappears from "xm list", which, in turn, will cause the monitor
operation to return a "not running" status.

If a monitor status returns "not running", then test status
again for wait_for_reboot seconds (perhaps it'll show up).

NOTE: This timer increases the amount of time the cluster will
wait before declaring a VM dead and recovering it.
</longdesc>
