It's single threaded.  That's why we have a lock on the library side.

We did have a look at making the daemon multithreaded, but it requires
us to stop using virtio-serial and use something else instead (there's
some alternate thing which I've forgotten the name of, but it doesn't
quite work for our use case because it uses global addresses for
ports).  IOW, it's complicated.
