Otherwise the private data entry would be kept across instances of the
same VM even if it's not configured to do so.

Does this mean we can kill the call to qemuDomainDestroyNamespace() from
qemuProcessHandleMonitorEOF() (and possibly the whole function)?

ACK either way, this should be cleaned up every time.

The comment there hints that it may be necessary in some cleanup cases,
so I did not remove it.

Thanks, there are no cleanup steps after that so clearing it is okay
either way.

I think that qemuDomainDestroyNamespace() would be better to use.
