Re: [libvirt] [PATCHv3] qemu: fix crash when mixing sync and async monitor jobs

Currently, we attempt to run sync job and async job at the same time. It

v3: incorporate Wen's feedback - in particular, virProcessStartCPUs
now checks for return type, restarting libvirt does not use an
async job, and I didn't hit the deadlock in the same scenarios as
I tested under v2.
I still need to do migration testing before I'm convinced that this
is right, but it's doing a lot better.

Nope, just got a deadlock, by sending SIGINT (^C) during the middle of virsh managedsave. I'll have to keep looking for that culprit...
