Marking Confirmed, I have experienced this too, and it seemed to start only when I updated about 24 hours ago.
Seems to be polling the sockets for each VM defined over and over without a 0 millisecond timeout. According to man 2 poll, a negative timeout is infinite, but it does not state that 0 is, so I can only assume that this is an error in some library call that should be specifying a timeout.
