When CMAP disconnects sbd results in 100% CPU usage.

This patch is currently used on SUSE, so upstreaming seem reasonable.

I think this has been tracked with #80 . Of course it probably needs to be revisited when we get a chance ...

Yep it is tracked there and was supposed to be solved together with corosync-graceful-shutdown detection/handling.
At that time this wasn't easily possible but meanwhile corosync has added back an api that should allow easy detection of a graceful corosync shutdown.
So this should be revisited asap.
I'll take it on my list of urgent stuff ;-)

But let me keep this open for now as the patch here is a bit more elaborate and takes care of how inquisitor should react. But as said without graceful-corosync-shutdown detection this is of limited use anyway.
